The swash plate is slidably coupled to the plurality of pistons and has a first hinge member extending from a surface of the swash plate. The first hinge member has a surface that has a cam profile. The rotor assembly has a rotor shaft and a rotor plate. The rotor plate has a second hinge member extending from a surface of the rotor plate, whereby the surface of the first member is configured to slide and rotate over the second hinge member forming a hinge about which the swash plate rotates.
