摘要: An independent metering valve (IMV) assembly is disclosed that includes a metering stem including an inlet. The IMV assembly also includes a hydro-mechanical control valve in communication with a fluid source and the inlet. The control valve also including a spool with a closed end and an open end. The control valve includes a biasing member that biases the control valve or spool towards an open position thereby establishing communication between the fluid source and the inlet. The control valve also including a load signal line providing communication between an outlet of the control valve upstream of the inlet and the closed end of the spool. Wherein high pressure in the load signal line allowing the control valve to move towards a closed position thereby overcoming bias of the biasing member and reducing flow to the inlet during a high pressure condition.

摘要: A hoist positioning system includes an accelerometer attached to a hoist, a control unit for processing signals from the accelerometer and comparing the processed signals with reference data to determine a position of the hoist, a drive system for moving the hoist up and down, and a relay that is switched ON and OFF by a control signal from the control unit. When the relay is switched ON, power is supplied to the drive system from a high-voltage power source and the hoist is driven up or down. When the relay is switched OFF, power from the high-voltage power source to the drive system is cut off and the hoist stops moving up or down.

摘要: A hydraulic system for a machine is disclosed. The hydraulic system has a source of pressurized fluid and a fluid actuator with a first chamber. The hydraulic system also has a first valve configured to selectively fluidly communicate the source with the first chamber. The first valve further includes a first element movable between a flow passing, at which fluid from the source flows to the first chamber, and a flow blocking position, at which fluid from the source is blocked from the first chamber and a second element configured to selectively drain a control passageway associated with the first element to cause the first element to move. The hydraulic system further has a proportional pressure compensating valve configured to control a pressure of a fluid directed between the source and the first valve dependent upon the pressure of the control passageway.

摘要: A valve for controlling fluid flow in a fluid system is disclosed. The valve includes a housing, a servo spool, and a piston. The servo spool defines a spiral groove and a spiral land. The piston defines an orifice configured to provide flow communication to a supply of pressurized fluid and an orifice configured to provide flow communication to a portion of the fluid system exterior to the valve. The valve further includes a main spool operably coupled to the piston. The main spool is configured to control flow of fluid in the fluid system. The spiral groove and spiral land are configured such that angular displacement of the servo spool results in a force imbalance on the piston, thereby moving the piston and the main spool in one of a first direction and a second direction.
