US 2024/0076843 A1 · HYDRAULICALLY-POWERED VACUUM SYSTEM

Abstract

A hydraulic implement, which may be configured for attachment to a hydraulic system having a pressure line and a return line, may include a motor, an anti-cavitation valve, and an adjustable flow control valve. The motor may be operably connected between the pressure line and the return line and to rotate a shaft when hydraulic fluid flows from the pressure line through the motor to the return line. The anti-cavitation valve may be connected in parallel across the motor between the pressure line and the return line. The adjustable flow control valve may be connected in parallel across the motor between the pressure line and the return line. A method may include causing fluid to flow from the pressure line through an open adjustable flow control valve to the return line; and at least partially closing the valve to divert at least some fluid flow through the motor.
