Abstract

1,259,755. Pistons. SULZER BROS Ltd. 24 April, 1970 [24 April, 1969], No. 19855/70. Heading F2T. [Also in Division F1] In a compressor wherein a piston 7 reciprocates in a cylinder 10 without normally making physical contact with the cylinder, the piston is provided with a split ring 25 having longitudinal grooves 26 in its periphery. The ring may be of P.T.F.E. and acts to guide the piston in the event of abnormal operation causing the piston to approach the cylinder. During normal operation gas escaping past labyrinth seals 20 or labyrinths formed in the periphery of the piston, acts on a conical ring 23 to centre the piston. Radial holes 30 pass through the ring 25 and open into the grooves 26 thereby to provide pressure equalization between the inside and outside of the ring. The piston may be double or, as shown, single acting and driven by a piston rod 6 which extends through a cylinder seal for connection to a cross-head.
