A built-in plunger hydrocylinder consists of a case, a plunger, an oil–supply device, rubber rings. The plunger is combined with the oil-supply device in one part, on the outer surface of which a metal retaining ring is arranged, and on the side from the central axle of the hydrocylinder a pin is disposed, in a dead opening of the plunger by one end, and in the bottom of the case by the other one. Between the movable parts, that is the plunger and a head of the cylinder, gaskets, which consist of rubber and protective fluoroplastic rings, are disposed and the hydrocylinder itself is arranged in bearings which take the external loading thereon. |
