Excavator Pump Parts Rexroth A10VO63 Valve Plate R902451804 Excavator Parts
Suction‑Discharge Commutation: Rotational movement of the cylinder block switches each plunger chamber between high‑pressure and low‑pressure ports to implement oil intake and outlet, replacing a separate directional valve assembly.
End‑face Sealing & Partition: Creates an oil film friction pair with the cylinder block end surface, maintaining separation between high/low pressure chambers and minimizing internal leakage.
Bearing Function: Supports hydraulic compression force and lateral plunger thrust, featured as one of the three critical friction pairs in hydraulic pumps and motors.
Vibration Damping & Noise Attenuation: Transition zones and pressure relief grooves weaken pressure impact, flow pulsation and running noise.
