  • Tire pressure management actuator with bypass leakage prevention
    Patent number: 5094263
    Abstract: 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.
