Two-stroke engine
A two-stroke engine equipped with a control device is described to control an operating condition of the engine. The engine consists of: a crankcase subjected to continuously alternating underpressure and overpressure conditions; an output actuator connected to the control device for adjusting the operating condition; pneumatic actuating means responsive to a change in pressure therein for acting on the output actuator so as to cause the latter to adjust the control device to control the operating condition; pressure connecting means for connecting the pneumatic actuating means to the crankcase; and, resonance valve means connected into the pressure connecting means for opening the latter in response to a predetermined resonance frequency thereby subjecting the pneumatic actuating means to one of the pressure conditions and causing a pressure change therein.
