摘要： A hydraulic system includes a poppet control valve having an inlet workport, a function workport, a control chamber, and a poppet arranged between the inlet workport and the control chamber. The poppet is movable between an open position and a closed position. The hydraulic system further includes a pilot control valve. A pressure correlated to the function workport is supplied to a first side of the pilot control valve and a pilot source pressure is supplied to a second side of the pilot control valve. When a pressure in the function workport reaches a setpoint pressure, the pressure correlated to the function workport forces the pilot control valve to a position that increases a flow restriction between the control chamber and the function workport, so that the poppet moves in a direction toward the closed position and limits the pressure in the function workport to the setpoint pressure.

摘要： An apparatus includes a first plurality of cylinders, each coupled to a shared first port by a separate first valve and to a shared second port by a separate second valve. Each first and second valve has a chamber to which pressure from either the associated cylinder or the respective port is dynamically applied to select different operating modes. Each one of a second plurality of cylinders is coupled to the first port by a separate third valve and to a shared third port by a separate fourth valve. Each third and fourth valve has a chamber to which pressure from either the associated cylinder or the respective port is dynamically applied to select different operating modes. Selecting an operating mode enables the apparatus to act as a bidirectional pump or a hydraulic motor. Selectively controller the valves can deactivate an individual cylinder, while other cylinders remain active.

摘要： A joystick for manually operating a pair of hydraulic valve members has a bracket to which a handle is attached. A pivot shaft rotationally extends between a pair of legs of the bracket and has a transverse aperture through which a pivot pin attaches the pivot shaft to a base of the joystick. This attachment structure allows the bracket to pivot with respect to the base about two orthogonal axes. A first link for coupling to one hydraulic valve member is pivotally attached to the pivot shaft, while a second link for coupling to another hydraulic valve member is attached by a ball joint to the bracket.

摘要： An apparatus and method for controlling variation in the pitch of an agricultural vehicle are disclosed. The apparatus includes a controller that controls a position of an implement attached to the agricultural vehicle, and a first valve that is coupled to, and receives a first control signal from, the controller. The apparatus further includes a suspension cylinder having a first chamber that is hydraulically coupled to the first valve. The first control signal provided from the controller is functionally related to a first additional control signal provided by the controller, and the first additional control signal is used to determine the position of the implement.

摘要： A return manifold includes a housing having a first workport, a second workport, a third workport, and a fourth workport, and defining a first chamber and a second chamber. The return manifold includes a back-pressure disk arranged between the first workport and the first chamber, a bypass disk arranged between the first chamber and the second chamber, a back-pressure spring biased between the back-pressure disk and the bypass disk, and a bypass spring biased against the bypass disk. The back-pressure disk and the bypass disk are hydro-mechanically coupled so that movement of the bypass disk alters a force on the back-pressure disk and movement of the back-pressure disk alters a force on the bypass disk.

摘要： A valve assembly (40) has a flow summation node (74) coupled to a displacement control (39) port of the first pump (50). Each valve (41-47) in the assembly has a variable metering orifice (75) controlling flow from an inlet (70) to a hydraulic actuator and has a variable source orifice (64) conveying fluid from a supply conduit (58) to a flow summation node. The source orifice enlarges as the metering orifice shrinks. Each valve includes a variable bypass orifice (80) and the bypass orifices of all the control valves are connected in series forming a bypass passage (85) between a bypass node (55) and a tank (53). The bypass node is coupled to the flow summation node and receives fluid from a second pump (51). At each valve, a source check valve (68) conveys fluid from the supply conduit to the inlet and a bypass supply check valve (89) conveys fluid from the bypass passage to the inlet.

摘要： A high efficiency diametrically compact, radial oriented piston hydraulic machine includes a cylinder block with a plurality of cylinders coupled to a first port by a first valve and to a second port by a second valve. A drive shaft with an eccentric cam, is rotatably received in the cylinder block and a cam bearing extend around the eccentric cam. A separate piston is slideably received in each cylinder. A piston rod is coupled at one end to the piston and a curved shoe at the other end abuts the cam bearing. The curved shoe distributes force from the piston rod onto a relatively large area of the cam bearing and a retaining ring holds each shoe against the cam bearing. The cylinder block has opposing ends with a side surface there between through which every cylinder opens. A band engages the side surface closing the openings of the cylinders.
