Abstract: A pump includes a housing defining an interior volume, and a diaphragm, where the diaphragm partitions the interior volume into a pumping chamber and an actuating chamber. The diaphragm is formed from a polymeric material, and the pump further includes a diaphragm support configured to limit a stroke of the diaphragm. The diaphragm support includes an array of apertures through which fluid passes to interface with the diaphragm during operation of the pump.

Abstract: A vehicle suspension system includes a pump, a gas spring, and an accumulator. The gas spring assembly includes a cylinder, a rod, and a chamber for supporting gas. The rod is coupled to the cylinder and moveable relative to the cylinder. The chamber is formed between the cylinder and the rod, where movement of the rod relative to the cylinder changes the volume of the chamber. The accumulator is configured for receiving, storing, and releasing potential energy from gas of the chamber. The accumulator is coupled to the chamber, and is in gaseous communication with the chamber such that a continuous body of gas extends between the chamber and the accumulator when the accumulator is receiving or releasing the potential energy.

Abstract: An electrochemical cell is provided having a cathode can that fits over an anode can to define an anode cavity for retaining active anode material. A cathode assembly is disposed proximal the base of the anode can, and is separated from the anode cavity via a separator. A radial seal is provided at the remote region between the outer periphery of the anode side wall and cathode side wall to prevent the leakage of electrolyte material. An insulator is disposed between the anode and cathode to provide electrical insulation therebetween.

Abstract: A rechargeable electrochemical cell is provided having a pressure-responsive apparatus for determining a charge termination point. In particular, a reversible pressure-responsive switch may be disposed in a rechargeable cell. A sensor determines when the switch has reacted in a predetermined manner, thus indicating that the internal pressure within the cell has reached a predetermined threshold. The sensor is part of sensing circuitry that is linked to a charger having automatic charging modes depending on the status of the sensing circuit.
