Abstract

Hydraulic piston engine has multiple pistons (8,10) arranged in the cylinder (4) limiting the working space (36) whereby suction valves (42,44) are arranged in pressurizing chamber with pressure control valve (38) to maintain the pressure in the chamber. The pressurizing medium flow path (62) is bounded by capillary tube.
