Abstract

833,874. Pistons. ALLINQUANT, F. S. Nov. 24, 1958 [Nov. 27, 1957], No. 37777/58, Class 122 (1). A free piston, particularly for an oleopneumatic shock absorber, comprises two rubber &c. washers 5 clamped, as by a bolt 1, between metal &c. members 4, 9 and having a diameter greater than the nominal diameter of the piston so that when the piston is assembled in the cylinder 11 the washers are deformed around the members 9 to form two oppositely directed cup packings. In a modification, Fig. 2 (not shown), the washers 5 are clamped back-to-back between two metal washers each having a reduced diameter portion around which the rubber washers are deformed in use to form cup packings.
