2065733 9201882 PCTABS00010 An apparatus includes a tilt piston (10) having a piston head (12). The piston head (12) is reciprocally disposed within a cylindrical bore (16) formed in a housing (14), the bore (16) being oriented along an axis. A seal (26) is mounted circumferentially about the piston head (12). The seal (26) has an outer diameter (27) that exceeds an inner diameter (56) of the cylindrical bore (16). The seal (26) extends radially in a first direction having an axial component. A support (52) is mounted circumferentially of the piston head adjacent the seal (26). The support (52) has an outer diameter (54) less than the outer diameter (27) of the seal (26). The seal (26) is a continuous annular ring which may be of a circular or rectangular cross section. The seal (26) and the support (52) may be formed as a unitary member or may be two distinct elements. The support (52) contacts the bore (16) during a portion of travel of the piston (10) within the bore (16).
