Abstract: A smart material actuator including a smart material stack and a compensator preventing expansion of the stack in a non-driving direction. When actuated, the smart material stack causes a force transfer surface to be driven in the driving direction, thereby actuating a first stage amplifier having two arms, which in turn actuates a second stage amplifier having two arms.

Abstract: A valve comprises a valve body having a fluid inlet and fluid outlet, a valve seat located in the valve body between the fluid inlet and a fluid outlet, a valve member movable towards and away from the valve seat for controlling the flow of fluid from the fluid inlet to the fluid outlet, and a PTC heater in thermal contact with the valve seat for heating the valve seat. The heater is integrated in the valve in a manner where the valve seat is used as an electrical conductor to facilitate operation and assembly of the valve, and a unique valve construction is provided for enabling self-draining to avoid accumulation of water or other liquid in the valve that might negatively impact performance of the valve.

Abstract: A rotary vane device comprising a rotor and a vane positioned in a pumping chamber in a housing for rotation about respective eccentric axes, wherein the rotor has a rotor slot in which the vane is positioned, characterized by the vane being driven and the rotor following the vane.

Abstract: A filter element and assembly for fluid applications which require a purging of air, and particularly for applications where the filter element is horizontally oriented (side loaded), where the filter element is rotationally positioned relative to the housing such that a vent orifice is properly located for venting air from the filter element as the element fills with fluid. The housing includes a cylindrical body with a closed end a threaded open end, and a threaded, cup-shaped cover which is screwed down onto the housing. The filter element and housing include i) cooperating retaining devices which temporarily couple the filter element to the housing cover when the element is initially inserted into the housing and the cover is initially screwed onto the housing; and ii) cooperating orientation devices which rotationally orient the filter element in the housing as the housing cover is further and fully screwed down onto the housing.

Abstract: A filter assembly includes housing enclosing a replaceable filter element. A support core is provided in the housing, and includes an extension and locking assembly. The element includes a ring of filtration media with a pair of end caps. The first end cap includes a central opening to receive the support core. The extension and locking assembly prevents the cover of the housing from being attached to the housing body without a proper filter element installed. The extension and locking assembly includes a bypass member and a locking member, which are in locking engagement when an element is absent in the housing. The second end cap includes internal protrusions which engage the locking member when the filter element is installed to disengage the bypass member from the support core, and allow the element to be inserted and the cover to be installed.

Abstract: A filter element removably located in a housing having a central valve structure. The element has an end cap with a valve actuating portion. The valve actuating portion includes a cylindrical portion and an annular base projecting radially inward from the cylindrical portion. The valve actuating portion includes a plurality of thin, flat keys spaced around the annular base and projecting radially inward from the cylindrical portion and axially outward from the base. The keys engage the valve structure in the housing when the element is installed, and open up a flow passage through the housing.

Abstract: A fuel cell system comprising a fuel cell stack and a layer assembly forming the fluid circuitry for the fuel cell stack. The layer assembly comprises a plurality of layers assembled in face-to-face contact and joined together in a fluid-tight manner. At least some of the layers integrate fluid-interacting devices and/or fluid-conveying channels. The layers have aligned openings for forming potential passageways through the layer assembly, and these passageways are partially opened and/or partially blocked to form the fluid circuitry.

Abstract: A hydrogen generation cartridge (12) for supplying hydrogen gas to the anode side of a fuel cell system. The cartridge (12) comprises a first compartment (30) containing a first reactant (32) and a second compartment (34) containing a second reactant (36). The first compartment (30) is positioned within the second compartment (34) and, prior to cartridge activation, the compartments (30,34) chemically isolate the reactants (32/36) from each other. To activate the cartridge (12), the first compartment (30) is opened (e.g., broken) to form a common chamber (40) with the second compartment (34), and the reactants (32/36) combine and react to generate hydrogen gas within this chamber 40.
