摘要： A charge relief mechanism for setting an oil pressure of a charge line which replenishes operating oil to a pair of operating oil lines fluidly connecting a hydraulic pump body and a hydraulic actuator, includes: an oil pressure setting line; and a charge relief valve inserted in the oil pressure setting line. The charge relief valve includes a relief valve body provided with a large diameter hole, a small diameter hole, and a check valve seat formed between the large diameter hole and the small diameter hole. The large diameter hole is provided with a check valve body which is seatable on the check valve seat and is movable in the axis line direction, and a slip-out prevention member for preventing the check valve body from being separated from the large diameter hole while allowing the check valve body to selectively communicate or block between the large diameter hole and the small diameter hole.

摘要： There is provided a working vehicle having first and second hydraulic pump units operatively driven by a driving source and arranged away to each other in a width direction of the vehicle. In the working vehicle, each of the first and second hydraulic pump units includes a pump body; a port block formed with an oil passage for supplying/discharging an operating fluid to/from said pump body; a pump case connected to the port block so as to define a pump body accommodating space for surrounding the pump body; and a pump shaft for rotatably driving the pump body, the pump shaft having an input end operatively connected to said driving source. A drain port for opening the pump body accommodating space outward and a charge suction port for drawing in an oil from an oil tank in order to supply a charge oil to a hydraulic circuit fluidly connecting with the corresponding hydraulic motor unit are provided respectively in first and second assemblies formed by the corresponding pump case and port block. The drain port is provided on a wall surface other than an opposing wall surface facing each other of the wall surfaces of said first and second assemblies when arranging the first and second assemblies so that the input ends of each pump shaft are directed in the same direction.

摘要： A hydraulic drive vehicle includes a bypass valve for fluidly connecting or disconnecting a pump/second-motor line and a second-motor/first-motor line, and set a capacity of a first hydraulic motor to a standard capacity which makes a peripheral speed of a first wheel driven by the first hydraulic motor equal to a peripheral speed of a second wheel driven by a second hydraulic motor when the bypass valve fluidly disconnects the two lines and set the capacity of the first hydraulic motor to a first capacity smaller than the standard capacity when the bypass valve fluidly connects the two lines. The present invention makes it possible to widen a variable range in which a traveling speed of the vehicle could be changed.
