RADIAL PLUNGER HYDRAULIC DEVICE USING HYDRAULIC CONTROL ONE-WAY VALVE FOR FLOW DISTRIBUTION, AND WORKING METHOD THEREOF

WIPO Patent Application WO/2022/222574

A1

A radial plunger hydraulic device using hydraulic control one-way valves for flow distribution, and a working method thereof. The radial plunger hydraulic device comprises a housing (200), several plunger assemblies, a spindle (300), first hydraulic control one-way valves of the same number as and corresponding to the plunger assemblies on a one-to-one basis, second hydraulic control one-way valves with the same number as and corresponding to the plunger assemblies on a one-to-one basis, and a flow distribution plate (400). The radial plunger hydraulic device using hydraulic control one-way valves for flow distribution provides a new flow distribution mode, and owing to the excellent sealing performance of the hydraulic control one-way valves, a hydraulic motor can work under high pressure and achieve a high volumetric efficiency. The device can be used as both a hydraulic motor and a hydraulic pump, and can be used in a hydraulic system that needs to achieve a power recovery function.
