    摘要： A pump displacement control cylinder is configured to control the displacement of a hydraulic pump according to pressure of hydraulic fluid and switches the discharge direction of the hydraulic fluid from the hydraulic pump according to the supply direction of the hydraulic fluid to the pump displacement control cylinder. A forward and backward progression switching valve is configured to switch the supply direction of the hydraulic fluid to the pump displacement control cylinder. A pressure control valve is configured to control the pressure of the hydraulic fluid supplied to the pump displacement control cylinder according to a command value input to the pressure control valve. A control section is configured to execute pump shuttle control which reduces the command value to the pressure control valve when switching between forward and backward progression using a forward and backward progression operation member.

    摘要： A hydraulic motor 11 is switched to a high-speed mode when pressure oil is supplied to a pressure chamber 23 of a tilt piston 17 based on the transmission of a speed signal to a high-low speed switching valve 18, and the hydraulic motor 11 is switched to a low-speed mode when pressure oil is discharged from the pressure chamber 23 of the tilt piston 17. A first braking purpose speed changing mechanism 13 operates so as to discharge pressure oil from the pressure chamber 23 of the tilt piston 17 when the pressure of pressure oil between a counterbalance valve 15 and a direction changeover valve 103 becomes equal to a tank pressure. Therefore, it is possible to provide a variable hydraulic motor driving device which is capable of preventing braking operation from being excessively long and also capable of preventing a large shock from occurring at a time of stoppage due to a large braking force generated from an early stage of braking operation.

    摘要： A self-sealing valve comprises a valve housing having a fluid conduit, a valve seat, and a retaining member, the valve housing being configured to pass fluid through the fluid conduit, and a flexible diaphragm comprising a flexible material having resiliency, wherein the retaining member and the flexible diaphragm are configured so that the retaining member retains a portion of the flexible diaphragm so as to use the resiliency of the flexible material to bias the flexible diaphragm against the valve seat to a closed position of the self-sealing valve to provide a self-seal of the fluid conduit, and to facilitate movement of the flexible diaphragm under a fluid bias against a first side of the flexible diaphragm in a first direction away from the valve seat to an open position, and wherein the retaining member and the flexible diaphragm are configured so that the self-sealing valve can be contacted to move a portion of the flexible diaphragm away from the valve seat to the open position.

    摘要： A hydrostatic drive system has a pump (1) and at least one consumer (5) controlled by a control valve (4) that can be actuated by control signals. A precharge device (10) that generates a precharge pressure is located in a reservoir line (7) that leads from the control valve (4) to a reservoir (2). The precharge device can be pressurized as a function of the control signals of the control valve (4). To make possible a recharge during the deceleration of a consumer, the precharge device (10) can be pressurized in the direction of an elevation of the precharge pressure when there is a decreasing control signal of the control valve (4).
