A one piece, molded plastic roller clutch cage has the heavy, rigid cross bars of adjacent pockets joined together by circumferentially flexible connecting members. The connecting members are located entirely within the space between pockets, and have no effect of the shape or structure of either the side rails or the cross bars of the pockets. When the cage expands or contracts with rising or falling temperatures, the curved connecting members can open or close, allowing the adjacent cross bars of adjacent pockets to move together or apart, thereby avoiding excess compression or tension in the cage.

A piston type TPM actuator valve has enough clearance between the piston and the wall of the cylindrical passage that it slides to prevent sticking, but still avoids excessive bypass leakage through the same clearance. A plug located in the passage between the piston and the check valve has a vent to atmosphere that prevents leaking air from compressing behind the advancing piston. The plug also carries a seal that is compressed when the piston bottoms out to prevent further venting.
