Opposed-piston engine, has gas interactive controller for controlling gas exchange by hydraulically moving sliding sleeves, and hydraulic actuators arranged around sliding sleeves and acting on sliding sleeves in sliding direction

摘要

The engine has a gas interactive controller for controlling a gas exchange by hydraulically moving sliding sleeves (16). Hydraulic actuators are arranged around the sliding sleeves and act on the sliding sleeves in a sliding direction. The hydraulic actuators are directly integrated as small hydraulic lifting pistons (1, 2) in parallel holes in which cylinders retain the respective sliding sleeves. A nose or a collar is provided at a free end of each actuator such that the actuators are immersed into a bore or recess located at an outer diameter in the sliding sleeves.
