摘要

A reciprocating hydraulic motor and pump assembly includes a cylinder and a piston disposed for reciprocation in the cylinder. The piston includes a stem having a bore extending longitudinally in the stem and a piston head connected to one end of the stem. The piston head includes a cavity communicating with the bore. A spool is slidably mounted in the stem bore and the piston head cavity. A magnetic latching assembly is disposed in the piston head cavity. A displacement rod is fastened to the piston rod. The hydraulic motor and pump assembly is used in an airless paint sprayer system.
