AI Technical Summary
Technical Problem
Existing multi-way valves have difficulty maintaining a stable pressure difference within the valve body when switching between different operating states, resulting in uncoordinated operation of the actuator.
Method used
The multi-way valve structure with a front-mounted pressure compensator uses a drive component to move the valve core to switch working ports, and uses the pressure compensator to maintain a constant pressure difference between the P port and the T port, thereby achieving mechanical interlocking and dynamic adjustment of the oil circuit.
Benefits of technology
This ensures that the pressure difference of the multi-way valve remains constant under different operating conditions, thus guaranteeing the stable operation and coordinated function of the actuator.

Abstract
This utility model discloses a multi-way valve for a pre-pressure compensator, including a valve body and a drive assembly. The valve body has a main valve chamber inside, and a main valve core is located inside the main valve chamber. The main valve core can slide along the main valve chamber via the drive assembly. The valve body surface has ports P, T, A, and B, all of which are connected to the main valve chamber. A pressure compensator is also located inside the valve body. Port P is connected to the main valve chamber through the oil inlet of the pressure compensator, and port T is connected to the oil return of the pressure compensator. The main valve core slides to switch the connection states of ports P and T with ports A and B, achieving mechanical interlocking of oil circuit on / off. This utility model provides a multi-way valve for a pre-pressure compensator. The drive assembly moves and switches the valve core, cooperating with the pre-compensator to compensate for the pressure difference in the working circuit, thereby maintaining a constant pressure difference between ports P and T of the valve body.
