Abstract

934,134. Pistons. CROSS MANUFACTURING CO. (1938) Ltd. June 14, 1962 [April 27, 1962], No. 16121/62. Class 122 (1). In a piston 1 the oil drainage holes 5 leading from the oil ring grooves 4 to the interior of the piston each have an axial length embracing two or more grooves (or convolutions in the case of a helical groove) and diverge inwardly to provide a larger mouth at the end spring into the piston interior than at the other end. In the embodiment shown in Figs. 1 and 2, the grooves 4 are helical and the holes 5 have outer circular mouths common to adjacent grooves and inner mouths in the form of slots with parallel sides. Grooves 2 are for a helical bearing and sealing ring (not shown). In modifications, the oil drainage holes bridge more than two grooves. Specification 929,162 is referred to.
