<p>A hydraulic system of multipurpose motion organization, having a housing (10) defining a cylinder, and an actuating shaft (40) installed in the housing, with ends of the shaft projected from the housing. A piston (20) is set in the cylinder to engage with the shaft, and a pressure control unit (60) is provided in the housing to partially close a part of oil passages (19a, 19b), thus controlling a load applied to the actuating shaft. The hydraulic system generates optimal exercise loads to be imposed on respective user, thus giving optimal exercise effects to the users. The system also allows the users to easily adjust the exercise loads, and has a simple structure, with reduced volume and weight, thus being conveniently installed at home or in a limited space of bulding.</p> |
