Description: |
| Abstract:
This invention relates to certain new and useful improvements in gas engines, and the particular feature of such engines that constitutes the subject of this invention is the device for regulating the quantity of the explosive agent or ingredient, which is to be mixed with atmospheric air to form the charge. This regulating device performs also, incidentally, the function of forcing the explosive ingredient into the air which forms the remainder of the charge, and in this sense this device is in the nature of a pump, one stroke of its piston acting to assist in raising the inlet valve and the other stroke operating to eject or force out the gasoline or gas taken in during the out-stroke. Combined with this piston is a hit-and-miss device consisting of a rod which strikes a blow to operate the said piston in one direction, and of a pivoted piece operated by a governor so as to move in and out of line with the striking bar, according to the speed of the engine, whereby when the speed is excessive the piston will not be actuated during one or more cycles of operation, whereby the explosive ingredient will not be taken in during the time of such excessive speed.
Claims:
1. In a gas engine, the combination with a cylinder and two valves, a supply pipe communicating with the cylinder through one of said valves and a discharge pipe communicating with the cylinder through the other of said valves, an air pipe into which the discharge pipe enters and a casing and valve permitting and cutting off communication between the air pipe and the main cylinder, a piston in the first named cylinder and a spring to force it outward, of a slotted piece pivoted to the piston, a governor whose shaft connects with said piece through said slot, and a reciprocating rod having a striking plate and actuated from the engine shaft.
2. In a gas engine, the combination with a cylinder having two valves, a supply pipe communicating with the cylinder through one of them, a discharge pipe communicating through the cylinder with the other, a piston working in the cylinder, a spring actuated rod connected with the piston, a piece pivoted to the piston and having a slot, a governor having a reciprocating shaft connected to the pivoted piece through said slot and a reciprocating rod adapted to strike the pivoted piece or not according to its position.
