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.

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.
