Description: |
| Abstract:
This invention relates to a structure of valve-casing and valves especially adapted for use in connection with gas engines but the use of which is not necessarily limited to gas engines. The invention relates to certain specific structural arrangements of the several parts of the valve casing and valves to be hereinafter specifically described in the specification and claimed.
In the construction heretofore of gas engines it has been customary, especially in engines of the larger sizes, to form the valve as a part of the cylinder structure, or in large sections to be attached to the cylinder structure, with the result that when the engine was assembled if it became necessary or desirable to disassemble the valve structure, it became necessary to disassemble practically the entire engine. In using certain kinds of gases to form an explosive mixture for the operation of the gas engine, it is found desirable, and in some cases absolutely necessary, to overhaul the valve casings, valves and gas passages adjacent thereto in order to remove deposits of tar, etc. which have accumulated.
Claims:
1. The combination with a cylinder provided with a port of a member provided with an aperture which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve casing secured to said cylinder and provided with a partition in the interior thereof to provide separate air and gas passages in said casing, the casing and its partition being provided with apertures, said apertures being larger than said member to permit said member to be withdrawn there through, a valve controlling the thoroughfare through the aperture of said partition, a-bonnet secured to said casing and closing one of the apertures therein, both of said valves being provided with stems extending into said bonnet, and means for operating said valves.
2. The combination with a cylinder provided with a port of a member provided with an aperture which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve-casing secured to said cylinder and provided with a partition in the interior thereof to provide separate air and gas passages in said casing; the casing and its partition being provided with apertures, being larger than said member to permit said member to be withdrawn there through, a plate provided with a thoroughfare contracting the aperture through said partition, a valve controlling the thoroughfare through said plate, a bonnet secured to said casing and closing an aperture therein, both of said valves being provided with stems extending into said bonnet.
3. The combination with provided with a port of a member provided with an aperture, which is smaller than said port, said member being secured to said cylinder with its aperture in alignment with said port, a valve seating upon said member, a valve casing secured to said cylinder and provided with a partition in the interior thereof provide separate air and gas passages in said casing, the casing and its partition being a cylinder provided with apertures, said apertures being larger than said member to permit said member to be withdrawn there through, a plate.
4. In combination with a gas engine cylinder a valve cylinder provided with apertures through which air may pass to the interior of said valve cylinder, one end` of said valve cylinder being open to the gas engine cylinder, a core extending into the valve cylinder forming an annular mixing chamber within the valve cylinder and an annular port at the other end of the valve cylinder through which gas may pass to the annular mixing chamber, and a valve controlling the port.
5. The combination with an engine cylinder of a valve casing provided with apertures, means for partially closing said apertures, valves located within said casing and, provided with stems which project through said casing to the outside thereof, said valves and the means for partially closing the apertures in 4said casing being so constructed. and arranged with respect to said casing that they are removable from the cylinder independently from the casing.
