摘要： A bypass/flushing valve (60) for a hydrostatic system includes a valve body including a central bore, a shuttle valve (66) located in the central bore (64), and a valve spindle (68) disposed within the central bore. The valve body includes four ports (90,92,94,96) each in communication with the central bore. The shuttle valve (66) blocks flow through the central bore (64) between a first port (90) and a second port (92). When pressure at the second port is higher than at the first port, the shuttle valve moves to allow flow passage between the first port (90) and the third port (94). When pressure at the first port is higher than at the second port, the shuttle valve moves to allow flow passages between the second port (92) and a third port (94). The spindle (68) is movable between a first position to block communication between the second port (92) and the fourth port (96) and a second position to allow for communication between the second port and the fourth port.

摘要： A method of operating a driveline including a powersplit transmission is provided. The driveline may be operated in a hydrostatic power transmission mode and a blended hydrostatic/mechanical power transmission mode. The method comprises the steps of providing a hydrostatic circuit, detecting a rapid deceleration of the vehicle, and adjusting a threshold of at least one pressure relief valve forming a portion of the hydrostatic circuit in response to the sudden deceleration. The at least one pressure relief valve facilitates quickly changing the driveline from the blended hydrostatic/mechanical power transmission mode to the hydrostatic power transmission mode.

摘要： A controller determines a target rotation speed of an engine from an operation amount of an accelerator operating member. The controller determines whether a vehicle is in coasting deceleration. The controller decreases a differential pressure between a first circuit and a second circuit of a hydraulic circuit according to a deviation between an actual rotation speed of the engine and the target rotation speed, or the operation amount of the accelerator operating member when the vehicle is in the coasting deceleration.

摘要： A hydrostatic continuously variable transmission is provided in which a hydraulic pump and a hydraulic motor are communicated to each other through a low pressure oil passage and a high pressure oil passage and a clutch valve capable of releasing an oil pressure of the high pressure oil passage is connected to the high pressure oil passage. The clutch valve can be automatically operated by making use of an oil pressure of the low pressure oil passage. A clutch valve is applied with an oil pressure of a low pressure oil passage for biasing the clutch valve in a valve opening direction, and an oil pressure governor is connected to a supply oil passage for supplying an oil pressure from an oil supply pump to the low pressure oil passage through a check valve for increasing an oil pressure of the oil passage in accordance with an increase in an input rotational speed of a hydraulic pump.

摘要： The invention refers to a hydraulic circuit for limiting the torque of a hydrostatic hydraulic motor connected in closed circuit to a hydraulic pump, which in braking mode operates as a hydraulic pump, in which pressure control valves are connected before and after the hydraulic motor. For the solution of this problem to develop such a hydraulic circuit which limits the maximum torque at the shaft of the hydraulic motor to approximately identical values independent of the fact whether the hydraulic motor is operated in the motor mode or in the pump mode, the pressure control valves consist of pilot-operated pressure control valves (6,7; 8,9). There is provided at least one on-off valve (5) which, when the hydraulic motor (2) is in the motor mode, switches the pilot-operated pressure control valve of the pressure side to a higher maximum pressure, and in pump mode it switches the pilot-operated pressure control valve of the other pressure side to a lower maximum pressure.
