  • Patent number: 10871293
    Abstract: A thermostatic radiator valve (TRV) assembly or automatic temperature balanced actuator (ABA) assembly controls a manifold assembly through a push pin bearing mechanism. The push pin bearing mechanism comprises a push pin that moves in a linear direction responsive to rotational movement of a motor gear that is coupled through a helical gear. Rotational movement of the push pin is prevented by a ball bearing assembly. Movement of the push pin is transferred to a manifold pin, which in turn, controls the manifold assembly. Because the push pin moves in a linear rather than a rotational fashion, erosion of the mated manifold pin is substantially reduced with respect to transitional approaches.
