ABSTRACT:
A compact high pressure fluid operated cylinder and method for making same is illustrated wherein an end cap is held within the cylinder by a snap ring (E) carried within a groove at the end of the cylinder to prevent axial dislodgement outwardly from the end of the cylinder, while an O-ring (A) is carried within complementary grooves (B) and (C) within an intermediate circumferential portion of the end cap opposite the snap ring and an opposite cylinder wall portion respectively to prevent inward dislodgement of the end cap. By inserting the snap ring within the groove (D) while an inner surface of the end cap is in engagement with the O-ring so as to resiliently position the end cap in sealing engagement between the snap ring and the O-ring with the end cap in spaced relation to an adjacent end of the cylinder, a cushion seal is provided preventing chattering of the end cap during operation.
