    摘要： A center section/motor sub-assembly for use in a hydrostatic transmission includes a center section having a pump running face for interfacing with a pump and a motor running face for interfacing with a motor, and a bore extending laterally through the center section from the motor running face. A spool valve is received in the bore and includes a fluid pathway for providing fluid communication between the pump running face and the motor running face. The sub-assembly further includes a motor having a rotor and a motor stator secured to the center section adjacent to the motor running face in a manner that permits rotation of the rotor. The center section is configured for the hydraulic separating forces of the motor to be reacted only into the center section. A hydrostatic transmission includes the sub-assembly enclosed by a housing, in combination with a pump and output shaft.

    摘要： An electronic regulator includes an inlet valve coupled to an inlet port, the inlet port configured to receive a supply pressure, and an exhaust valve coupled to an exhaust port, the exhaust port configured to release a pilot pressure when the exhaust valve is open. The electronic regulator also includes a pilot pressure output pneumatically coupled to the inlet valve and exhaust valve and configured to be coupled to an external process control device to provide the pilot pressure to the external process control device. A setpoint input coupled to both the inlet valve and the exhaust valve receives a setpoint signal indicative of a setpoint value, and the electronic regulator operates the inlet valve and the exhaust valve to control the pilot pressure according to the setpoint value. Further, the electronic regulator includes a vent valve coupled to a venting port and pneumatically coupled to the pilot pressure output. The venting port is configured to release the pilot pressure according to the safety control signal.

    摘要： The present invention relates to a pressure reducing apparatus. A diaphragm made from an elastic material is provided in the interior of a body. The diaphragm includes a main body portion having a seat member that is capable of being seated on an inner tubular member of the body, a retaining portion disposed on an outer peripheral side of the main body portion and which is slidably displaceable with respect to the inner tubular member, and a skirt that is retained on a flange of the body. Additionally, by flexing of the skirt by means of an elastic force of a spring, the seat member thereof separates away from the inner tubular member.

    摘要： A hydraulic system including a first cylinder conduit configured to couple to a cylinder, an auxiliary conduit configured to couple to a case drain conduit, and a pressure regulator coupled to the first cylinder conduit and to the auxiliary conduit. The pressure regulator may block fluid flow to the auxiliary conduit if a first fluid pressure is less than or equal to a threshold pressure and enable fluid flow if the first fluid pressure is greater than the threshold pressure. The hydraulic system further includes a supplemental conduit with a check valve that directs fluid from the auxiliary conduit to a reservoir. The check valve blocks fluid flow if a second fluid pressure is less than or equal to a third fluid pressure, and enables fluid flow if the second fluid pressure greater than the third fluid pressure.
