Abstract: A tire inflation system including a drive mechanism having a rotational axis, a pump cavity positioned a radial distance away from the axis of rotation, and a force translator coupling the rotational axis to the pump cavity. The drive mechanism includes a cam comprising an arcuate bearing surface having a non-uniform curvature, the cam rotatable about the rotational axis, and an eccentric mass couple to the cam that offsets a center of mass of the drive mechanism from the rotational axis. The pump cavity is rotatably coupled to the cam, wherein the pump cavity includes an actuating element and a chamber. The force translator couples the arcuate bearing surface to the actuating element, wherein the force translator includes an axis having an arcuate position fixed to an arcuate position of the pump cavity.

Abstract: A pump system including a drive mechanism that provides a pumping force, a primary pump including a first pump cavity, an actuating element in reciprocal relation with the first pump cavity, and an outlet fluidly connected to a reservoir, a force translator that facilitates pump force transfer from the drive mechanism to the actuating element, a pressure regulation mechanism including a reciprocating pump that includes a pump chamber including an inlet manifold fluidly connected to the reservoir, a valve located within the inlet manifold, and a reciprocating element in reciprocal relation with the pump chamber. The pressure regulation mechanism preferably passively ceases force transfer from the drive mechanism to the primary pump based on the pressure of the reservoir.
