ABSTRACT:
A wobble piston apparatus incorporates a cup-type seal seated on a land formed about the head of the piston, and secured by an annular ring. The head of the piston and the ring have chamfered edges which facilitate an engagement of the ring with the piston head, on assembly, and the chamfered edge of the ring further cooperates with the piston to define a void which accommodates therein an extruded expansion of an innermost, peripheral edge of the seal.
