Abstract
PURPOSE: To improve the cushion effect by providing the cushion members having a circular projection at one ends of a cylinder cover and a piston respectively such that they will be fitted each other thereby preventing the collision of the piston against the cylinder cover.
CONSTITUTION: A cushion plunger 23 having a circular projection 25 is formed on a piston 21 while a cushion member 27 having a circular groove 28 to be fitted with said projection 25 with the gap S1 is formed on the head cover 2 and a circular projection 29 to be fitted with a circular groove 26 with the gap S2 is further formed. When the piston will move to the right the cushion plunger 23 is fitted with a cushion member 27 to reduce the flow path area thus to produce the high pressure in the chamber A and to provide the resistance against the piston 21. Consequently the cushion effect can be improved when compared with the conventional one by the resistance of the pressurized oil flowing in the gaps S1, S2.
