Abstract
PURPOSE: To improve the sucking property and the reverse sealing property by defining a pressure chamber and a liquid supply chamber in a cylinder chamber, while allowing passage of a liquid, and by forming a cup seal on the outer circumference of a piston at the pressure chamber side.
CONSTITUTION: The flange portion 105 of a piston 3, which is accommodated in a cylinder chamber 2, is divided into a pressure chamber 6 and liquid supply chamber 7, both of which are made to have communication with each other through a clearance 108 between the flange 105 and the inner wall 15 of the cylinder chamber 2. A cup seal 112 is positioned adjacent to the flange portion 105 and on the outer circumference of the piston 3 at the pressure chamber side 6 such that it allows the passage from the pressure chamber 6 to the liquid supply chamber 7 but inhibits the opposite passage. A radially expanding clearance 119 is formed in the annular shape between the back portion 116 of the cup seal 112 and the end face 105A of a flange 105 so that the sucking property and the sealing property in the opposite direction can be improved.
