摘要： Consistent with an aspect of the disclosure, a method for controlling a hydraulic cylinder is provided. The hydraulic cylinder is provided with a chamber and configured to receive fluid from a valve. The method includes receiving a user input and determining a desired velocity of the hydraulic cylinder in accordance with the user input. In addition, the velocity of the hydraulic cylinder is measured and a position of the valve is determined in accordance with the desired velocity of the hydraulic cylinder and the measured velocity of the hydraulic cylinder. The method further includes determining a desired force to be applied to the valve in accordance with a difference between the desired and measured velocities of the hydraulic cylinder, and actuating the valve in accordance with the desired force to thereby inject the fluid into the chamber and move the hydraulic cylinder.

摘要： A poppet valve assembly with a control chamber that can be fluidly connected to a number of different hydraulic ports via a pilot valve assembly. The poppet valve assembly includes a poppet valve member whose movement is controlled by filling or draining the control chamber, and which can be hydraulically locked into a given position by fluidly isolating the control chamber from any other hydraulic connections. The poppet valve member includes a control hydraulic surface exposed to fluid pressure in the control chamber. The poppet valve assembly may be part of a valve assembly that includes a plurality of poppet valve assemblies that operably control a hydraulic cylinder connected to an implement of a work machine.

摘要： A spool valve includes a valve housing. The valve housing may include a cavity, a first passage extending from the cavity, and a plurality of ports connected to the cavity. The spool valve may also include one or more components blocking the first passage, including a spool valve element disposed in a first position at least partially within the cavity. The spool valve element may be moveable to one or more other positions wherein the spool valve element leaves the first passage unblocked.

摘要： A valve for a fluid circuit is disclosed. The valve has a main valve element with a first end and a second end. The main valve element is movable between a flow-passing and a flow-blocking position in response to fluid pressure exerted on the first and second ends. The valve also has a solenoid mechanism operatively associated with the main valve element to move the main valve element toward one of the flow-passing and the flow-blocking positions. The valve further has a main valve spring configured to bias the main valve element in opposition to movement caused by the solenoid mechanism. The valve additionally has a relief valve element configured to communicate a fluid with the first end of the main valve element in response to a fluid pressure to initiate movement of the main valve element.
