    Abstract: A latching electromechanical actuator (9) includes a soft iron armature (31) movable between first and second positions, a permanent magnet (5A), a solenoid (23), and a soft iron external frame (11). The permanent magnet (5A) may be stationary relative to the solenoid (23) and operative to hold the armature (31) stably in either the first position or the second position. The actuator (9) provides two distinct magnetic flux paths (24A, 24B), one or the other of which is the primary flux path for the permanent magnet (5A) depending on whether the position of armature (31). Both flux paths pass through the armature (31). One of the flux paths may pass through the external frame (11). The other does not. The actuator (9) may include two permanent magnets (5) performing complementary roles for the first and second positions. The actuator (9) can be simply constructed, compact, and highly efficient.

    Abstract: A self-regulating pressure throttle configured for use in a fluid conduit includes a throttle body having a series of segments. The throttle body includes an inlet end and an outlet end. The throttle body includes a cone portion and a rim portion. The cone portion tapers away from the rim portion from a first end to a second end. The second end includes a nozzle orifice. The series of segments can be formed on the cone portion. The series of segments are configured to move between (i) a first position wherein the nozzle orifice has a first diameter and (ii) a second position wherein the nozzle orifice has a second diameter. The second diameter is smaller than the first diameter. The series of segments can be configured to move from the first position to the second position upon an increased pressure flow of fluid at the inlet end.

    Abstract: A fuel tank system constructed in accordance to one example of the present disclosure includes a fuel tank, a purge canister, a valve assembly and a bypass means. The valve assembly can be fluidly coupled between the fuel tank and the purge canister and that selectively controls fuel vapor flow between the fuel tank and the purge canister. The bypass means can selectively bypass fuel vapor around at least a portion of the valve assembly from the fuel tank to the purge canister. The bypass means can include a bypass valve.
