Title:
HYDRAULIC PRESSURE CONTROL SYSTEM FOR REDUCING MOTOR CAVITATION
Document Type and Number:
Japanese Patent JP2003239904
Kind Code:
A
Abstract:
To provide a hydraulic pressure control system for reducing motor cavitation.
The fluid control system comprises at least one double-acting cylinder and at least one fluid-driven motor. A pressure fluid source feeds the pressure fluid flow to the at least one double-acting cylinder and at least one fluid-driven motor, and a tank receives the return fluid flow from the at least one double-acting cylinder and at least one fluid-driven motor. A back pressure element is disposed between the tank and the motor, and may affect the back pressure condition of the fluid emitted from the motor. An exclusive channel may feed the supply fluid to the motor at a location between the motor and the back pressure element.
