| Abstract:
This invention relates to a fuel-mixing device or valve for gas engines, &c., whereby the relative proportion of air and gas may be varied and the quantity of fuel supplied to the engine may be regulated.
The object of this invention is to produce an improved mixing device or valve of this character which is simple in construction, reliable in operation, and which can be readily adjusted.
Claims:
1. A fuel-mixing device, comprising an air-supply, a gas-supply, two cooperating volume-controlling members, one of which is movable relatively to the other and one of which has a port, and a separating member arranged between the air-supply and the gas-supply and entering said port and having its edge flush with the joint between the last named members, said separating member and the cooperating volume-controlling member being movable one relatively to the other for varying the proportion of air and gas, substantially as set forth.
2. A fuel-mixing device comprising an air-supply, a gas-supply, a volume-controlling device having a member provided with a port, a partition or separating member arranged between the air-supply and the gas-supply, one of said members being movable relatively to the other for varying the proportion of air and gas, and a filling-piece arranged in said port and maintained in a definite relation to said separating member, substantially as set forth.
3. In a fuel-mixing device, the combination of an air-supply, a gas-supply, a volume-controlling device having a member provided with a port, and a partition or separating member arranged between the air-supply and the gas-supply and having an extension entering said port, one of said members being adjustable relatively to the other for varying the proportion of air and gas, substantially as set forth.
4. In a fuel-mixing device, the combination of an air-supply, a gas-supply, a valve member having a port, and a partition arranged between the air-supply and gas-supply and movable relatively to said port, substantially asset forth.
5. In a fuel-mixing device, the combination of an air-supply, a gas-supply, a valve member having a port which communicates with both the air-supply and the gas-supply, and an adjustable partition which is arranged in said port and between the air and gas supplies, substantially as set forth.
6. In a fuel-mixing device, the combination of an air-supply, a gas-supply, a valve member having a port and movable in one direction for varying the quantity of air and gas, and a partition which is arranged between the air-supply and gas-supply and which is movable in another direction for varying the proportions of air and gas, substantially as set forth.
7. In a fuel-mixing device, the combination of an air-supply, a gas-supply, two cylindrical valve members fitted one within the other and one movable with reference to the other for varying the quantity of air and gas, and a partition arranged between the air and gas supplies and movable for varying the proportions of air and gas, substantially as set forth.
8. In a fuel-mixing device, the combination of an air-supply, a gas-supply, two cylindrical valve members fitted one within the other and one rotatable with reference to the other for varying the quantity of air and gas, and a partition arranged between the air and gas supplies and adjustable axially with reference to the valve members for varying the proportions of air and gas, substantially as set forth.
9. In a fuel-mixing device, the combination of an air-supply, a gas-supply, two concentric valve members one rotatable with reference to the other for varying the quantity of air and gas, and one of said members communicating at opposite ends with the air and gas supplies, and a partition arranged in the inner valve member between the air and gas supplies and capable of axial adjustment relatively thereto for varying the proportions of air and gas, substantially as set forth.
10. In a fuel-mixing device, the combination of an air-supply, a gas-supply, two concentric valve members having coinciding ports in their sides and one member rotatable with reference to the other for varying the quantity of air and gas, a partition arranged between the air and gas supplies and adjustable axially with reference to the valve members for varying the proportions of air and gas, and filling-pieces arranged on the partition and fitting into the ports of the adjacent valve member, substantially as set forth.
11. In a fuel-mixing device, the combination of an air-supply, a gas-supply, inner and outer cylindrical valve members having coinciding ports in their sides, one of said valve members being rotatable with reference to the other for varying the quantity of air and gas and said inner valve member communicating at opposite ends with the air and gas supplies, a partition arranged in the inner valve member and capable of axial adjustment therein for varying the proportions of air and gas, and filling-pieces arranged on the partition and fitting into the ports of the inner valve member, substantially as set forth.
12. In a fuel-mixing device, the combination of an air-supply, a gas-supply, inner and outer cylindrical valve members having coinciding ports in their sides, said inner member communicating at its opposite ends with the air and gas supplies, a movable spindle to which the inner valve member is secured, and a partition arranged in the inner valve member between the air and gas supplies and capable of axial adjustment therein, substantially as set forth.
13. In a fuel-mixing device, the combination of a valve-body having a mixing-chamber, and gas and air supply chambers on opposite sides of the mixing-chamber, a cylindrical valve-casing fitting in the partitions between the mixing-chamber and the air and gas chambers and provided with ports opening into the mixing-chamber, a cylindrical valve-barrel rotatable in said casing and provided in its side with ports adapted to register with the ports of the casing, and a partition arranged in the valve-barrel between the air and gas supplies and capable of axial adjustment therein, substantially as set forth.
14. In a fuel-mixing device, the combination of a valve-body having a mixing-chamber and gas and air supply chambers on opposite sides of the mixing-chamber, a cylindrical valve-casing fitting between the mixing-chamber and the air and gas chambers and provided with ports opening into the mixing-chamber, a cylindrical valve-barrel rotatable in said casing and provided with ports adapted to register with the ports of the casing, a partition arranged in the valve-barrel between the air and gas supplies, a spindle journaled on the valve-body and connected with the valve-barrel, a sleeve mounted on the spindle and connected with the partition, and an adjusting device whereby the partition and its sleeve are moved axially with reference to the valve-barrel, substantially as set forth.
15. In a fuel-mixing device, the combination of a valve-body having a mixing-chamber and gas and air supply chambers on opposite sides of the mixing-chamber, a cylindrical valve-casing fitting between the mixing-chamber and the air and gas chambers and provided with ports opening into the mixing-chamber, a cylindrical valve-barrel rotatable in said casing and provided with ports adapted to register with the ports of the casing, a partition arranged in the valve-barrel between the air and gas supplies, a spindle journaled on the valve-body and connected with the valve-barrel, a sleeve mounted on the spindle and connected with the partition, a slide guided on the valve-body, a fork mounted on the slide and engaging with an annular groove in said sleeve, and an adjusting-screw connecting the slide with the valve-body, substantially as set forth.
