Excavator Pump Parts PSVL-54 Valve Plate RD20169040 Excavator Parts Flow Distribution & Commutation: As the cylinder block rotates, each plunger chamber is automatically alternately connected to the high-pressure and low-pressure oil ports to complete oil suction and discharge, replacing a separate directional valve. Sealing & Isolation: Forms an oil film friction pair with the end face of the cylinder block, isolates high and low pressure chambers, and prevents internal

Excavator parts AP2D25 VOE 14520404 Piston Shoe Set Of 10 Pc For Hydraulic Pump Parts Force Transmission and Angle Self-Adaptation Inside the cylinder block, the piston moves back and forth linearly, whereas the swash plate is fixed at an inclined angle. Connected by a spherical hinge, the piston shoe can swing freely matching the swash plate’s inclination and steadily transmit the piston’s axial thrust to the swash plate. Removing the piston shoe would let the piston ball

SBS140 188-4210 PISTON SHOE 9 PCS FOR CAT 324D 325D 328D 329D 325C HYD PUMP Force transmission and spherical self‑adaptation (spherical hinge pair) The inner spherical socket of the piston shoe embraces the piston ball head to form a universal spherical hinge. The thrust generated by reciprocating motion of the piston is transmitted to the swash plate via the piston shoe. As the pump rotates, the piston shoe can swing freely and maintain constant contact with the plane of the
