Abstract

PURPOSE:To prevent the generation of heat by friction as well as reduce vibration and noise by dividing a housing into an air chamber and a liquid chamber with a flexible air-tight sheet and connecting the liquid chamber to a liquid pump through a four-way switch valve. CONSTITUTION:A housing 1 is divided into an air chamber 3 and a liquid chamber 4 with a flexible air-tight sheet 2, and the liquid chamber 4 is connected to a liquid pump 11 through a four-way switch valve 10. Thus, since the air-tight sheet 2 operates inside the housing 1, vibration and noise generated by the movement of the air-tight sheet 2 can be greatly lowered, and also since the air-tight sheet 2 has no sliding part, the generation of heat by friction can also be prevented.
