Compressor with variable displacement in accordance with angle of inclination of drive disc arranged in crankcase has piston connected to drive disc and reciprocated by movement of drive disc

摘要

An adjustment mechanism (48,49) is provided for the pressure in the crankcase (15) and has a control through passage (48) connected with the crankcase, permitting passage of a fluid. A control valve (49) is arranged in the control through passage, selectively opening and closing it. The inclination of the drive disc (23) varies in accordance with the pressure in the crankcase and the stroke of the piston (36) varies in accordance with the inclination of the drive disc in order to alter the displacement. A fixed limiter is arranged in the control through passage, in order to limit the flow rate of the fluid in the control through passage.
