OPPOSED PISTON ENGINE WITH GAS EXCHANGE CONTROL BY MEANS OF HYDROSTATICALLY MOVED SLIDING SLEEVES

摘要

The invention relates to an opposed piston engine with gas exchange control by means of sliding sleeves, said sliding sleeves being embodied on the outer periphery thereof, as differential pistons and as a result can be operated as slave pistons. A plunger that is displaced by a cam is used as a master piston. A hydraulic liquid is housed between the master piston and the slave piston in a closed pipe system. The liquid column housed between the master piston and the slave piston can be displaced back and forth by means of hydrostatic pressure build-up thus enabling the gas exchange elements to be opened and closed by the sliding sleeves.
