    Abstract: Piston actuators and methods of its operation are described. The piston actuators include a housing defining a chamber having a piston therein and a spring seated against the piston to bias it into a starting position. The piston includes a ferromagnetic material, a magnet or both and a secondary magnet or ferromagnetic material, forming a first magnetic/ferromagnetic pair with the piston, is positioned to maintain the piston in a secondary position. A tertiary magnet or ferromagnetic material, forming a second magnetic/ferromagnetic pair with the piston, may assist the spring in maintaining the piston in the starting position. During operation, introduction into or removal from the chamber of an amount of fluid sufficient to overcome the force of the spring (and the tertiary magnet or ferromagnetic material) enables the attraction between the members of the first magnetic/ferromagnetic pair to move the piston to the secondary position as a snap movement.

    Abstract: Check valves, Venturi devices and engines that include the check valves are disclosed. The check valves define an internal cavity having a first port and a second port, a first seat and a second seat, and a translatable seal disk. The first seat is proximate the first port and has a first annular seal bead, and a second annular seal bead radially inward from the first annular seal bead. The seal disk has a first sealing portion seatable against the first annular seal bead and a second sealing portion seatable against the second annular seal bead (both of a first thickness), an intermediate portion between the first and second sealing portions of a second thickness, and a lip portion defining the outer periphery of the seal disk of a third thickness. The second thickness is greater than the first thickness, and the third thickness is less than the first thickness.

    Abstract: A vacuum producer for supplying vacuum to a device in a boosted engine air system is disclosed. The boosted engine air system includes a throttle. The vacuum producer includes a first engine connection, a second engine connection, an aspirator, an aspirator check valve, an ejector, and an ejector check valve. The first engine connection is fluidly connected to atmospheric pressure and the second engine connection is fluidly connected to the engine air system at a location upstream of an intake manifold of an engine and downstream of the throttle. The aspirator provides vacuum to the device if pressure at the intake manifold is below atmospheric pressure. The ejector provides vacuum if pressure at the intake manifold is above atmospheric pressure.
