Appl. No.:

09/641325

Inventors:

Michael J. French - Pleasant Prairie WI
Eric A. Criteser - Libertyville IL

Assignee:

Bombardier Motor Corporation of America - Grant FL

International Classification:

F04B 1924

US Classification:

417 53, 417415

Abstract:

A reciprocating pump includes a drive section and a pump section. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied by a reciprocating circuit during operation. A permanent magnet structure of the drive section creates a magnetic flux field which interacts with an electromagnetic field produced during application of the control signals to the coil. Depending upon the polarity of the control signals applied to the coil, the coil is driven in one of two directions of movement. The reciprocating circuit employs a storage capacitor and several switches to capture the energy of the reciprocating coil as the pump is driven downwardly. The charge is recycled as the capacitor dissipates, thereby reversing the polarity of the current through the coil and driving the coil assembly upwardly to its initial position. A drive member transfers movement of the coil to a pump element which reciprocates with the coil to draw fluid into a pump chamber and expel the fluid during each pump cycle. The pump is particularly well suited to cyclic pumping applications, such as fuel injection systems for internal combustion engines.

Assignee:

Bombardier Recreational Products Inc. - Valcourt

International Classification:

F02N011/00

US Classification:

290 40R, 290 39 R, 440113

Abstract:

An engine control unit enablement circuit is disclosed that selectively closes a conductive path between a chargeable electrical energy source and electronics of an engine/motor. An engine position sensor provides feedback as to the rotational position of a rotating component of an engine to the enablement circuit. When the rotating component, e. g. crankshaft or flywheel, is rotating, the enablement circuit closes the conductive path and allows the transference of electrical energy from the energy source to the engine and motor electronics. Conversely, when feedback is received indicative of non-rotation of the rotating component, the enablement circuit opens the conductive path. As such, energy stored in the energy source remains stored. With a subsequent detection of rotation of the rotating component, the conductive is closed and the stored energy is allowed to pass to the engine and motor electronics thereby allowing faster powering of the engine and motor electronics.
