摘要： A hydrostatic transmission constructed so that a check valve and a relief valve are made as compact as possible to supply oil to a closed circuit for connecting a hydraulic pump and a hydraulic motor, and to regulate maximum pressure in the closed circuit. A check valve and a relief valve are contained in a valve casing. A valve body of the relief valve is disposed opposite to a valve body of the check valve. A relief spring of the relief valve is retained by a cover detachably mounted to an open end of the valve casing, thereby facilitating pressure setting of the relief valve. The valve body of the relief valve is contained in a relief valve casing slidably disposed in the valve casing. A plunger, capable of urging the check valve in the opening direction via the relief valve casing, is provided in the cover, thereby enabling the check valve to be manually opened.

摘要： A variable displacement hydraulic system contains a housing, a cylinder block provided with a plurality of pistons movable in reciprocation, and a swash plate for controlling reciprocation of each of the pistons so that the swash plate is slantwise rotatable along a slidable contact surface of arcuate shape. A thrust metal is mounted to an arcuate contact surface of the housing. Arcuate plates having smooth surfaces of high sliding efficiency are fixed onto outwardly curved portions formed at the rear surface of the swash plate, which is in contact with the thrust metal. Alternatively, a smooth surface layer having a high sliding efficiency is formed on the swash plate by applying chemical processes, thereby reducing the sliding resistance of the swash plate and improving the ease with which the swash plate is restored to the neutral position.

摘要： In a valve mechanism for controlling oil pressure in an oil path (13) connecting between a hydraulic pump (11) and motor (12) of a hydrostatic transmission (10), a differential piston (23) serving as a relief valve member for gradually increasing the oil pressure has a larger pressure-applied surface area at the side opposite to the oil path than at the side of this path. A throttled oil passage (24) is provided for conducting oil pressure in the path to the larger surface area. The piston is biased by a valve spring (25) through a control piston (26). A receiving member (27) for the spring and a stopper member (28) for the control piston are provided such that they are adjustable in position independently of each other. By this, the manner of increasing the oil pressure may be adjusted in a large variety. The valve mechanism also serves as a relief valve for excluding a possible, excessively high pressure.
