Abstract
7075. Main, J. A. April 4. Gas and like engines; valves and valve-gear.- The inlet valve is closed by a solenoid. Thespindle A is fitted with an iron plunger B passing through a solenoid C, the current for which is supplied by a storage battery, magneto machine, or other source. The weight of the valve E and plunger B is taken by a light helical spring F, fitted around the valve-spindle or an extension A' thereof, so that the valve E is. easily opened by the suction of the motor, and is smartly closed by the solenoid at, before, or after the commencement of compression. The compression of the spring F can be adjusted by the nuts H. Governing.-A timing-switch may be conveniently arranged to bring the solenoid C into action at an earlier or later period of the engine stroke, to vary the supply of combustible or the degree of compression.
