Electromagnetically actuated low pressure drain valve for use in swash-plate type axial piston machine utilized as hydraulic motor, has main coil and auxiliary coil producing magnetic force acting valve body in respective directions

摘要

The valve (22) has a valve body (40) associated with sealing surfaces (72, 74) and mechanically prestressed towards an opening position. The valve body is shifted in another direction in a closing position using a magnetic actuator. A main coil (50) and an auxiliary coil (52) produce magnetic force acting on the valve body in the respective directions. The main and auxiliary coils are arranged coaxial to each other. A main anchor (54) and an auxiliary anchor (56) are assigned to the main and auxiliary coils, respectively.
