Abstract
A piston for use in a reciprocating piston machine having a wobble plate has a first segment and a second segment axially spaced from and aligned with the first segment. A bridge segment connects the first and second piston segments for simultaneous reciprocal movement and at least one body is attached to the bridge segment to connect the piston to a wobble plate.

A piston for use in a reciprocating piston machine having a wobble plate, said piston having a first piston segment and a second piston segment axially spaced from and aligned with said first piston segment, a bridge segment connecting said first and second piston segments for simultaneous reciprocal movement, and a means for operatively connecting said piston to a wobble plate, whereby a relative velocity perpendicular to the center axis of said piston and tangential to a wobble plate occurs between said piston and said wobble plate during reciprocal movement of said piston, wherein said means for operatively connecting said piston to said wobble plate includes a cavity in said bridge segment and two support bodies mounted within said cavity in said bridge segment which are adapted to lie on opposed sides of said wobble plate wherein each of said two support bodies mounted in said bridge segment is a segment of a sphere and said segments have coaxial mean perpendiculars wherein said piston has opposed ends for one of the displacement of a pressure medium and the pressurization of a pressure medium.
A piston for use in a reciprocating piston machine having a wobble plate, said piston having a first piston segment and a second piston segment axially spaced from and aligned with said first piston segment, a bridge segment connecting said first and second piston segments for simultaneously reciprocal movement, and means for operatively connecting said piston to said wobble plate, said means including a cavity in said bridge segment and two support bodies mounted within said cavity in said bridge segment and adapted to lie on opposite sides of said wobble plate, pressure pockets formed in said bridge segment adjacent each said support body creating hydrostatic bearings on a surface of each said support body within said bridge segment, and a pressure pocket formed on a surface of each said support body facing said wobble plate whereby a hydrostatic bearing is formed between said support bodies and said wobble plate, whereby a relative velocity perpendicular to the center axis of said piston and tangential to a wobble plate occurs between said piston and said wobble plate during reciprocal movement of said piston.
