47252081, Feb 16, 1988

Filed:

Mar 10, 1986

Appl. No.:

6/837840

Inventors:

Ralph V. Brown - Cayuta NY

Assignee:

Facet Enterprises, Inc. - Tulsa OK

International Classification:

F04B 1704

US Classification:

417417

Abstract:

A positive shut-off electromagnetic fluid pump of the type having a piston electromagnetically reciprocated in a cylindrical guide by a solenoid coil and a pair of valves for providing a unidirectional fluid flow from an inlet port to an outlet port in response to the reciprocation of the piston. An elastomer bumper attached to the piston occludes the outlet port when the piston is biased to its extreme position adjacent to the outlet port when the solenoid coil is de-energized.

Assignee:

Facet Enterprises, Inc. - Tulsa OK

International Classification:

F04B 1704

US Classification:

417417

Abstract:

A high pressure electromagnetic reciprocating fluid pump is disclosed herein. The pump has a pair of telescoping cylinders axially disposed inside a generally cylindrical cavity of a pump housing. Unidirectional valves disposed at the opposing ends of the telescoping cylinders cause a unidirectional fluid flow through the pump as the telescoping cylinders are reciprocated relative to each other by a solenoid driven armature.

US Classification:

417417

Abstract:

A low pressure metering pump having a hollow piston reciprocated in a cylindrical guide by a solenoid coil. A pair of check valves provide for unidirectional fluid flow through the cylindrical guide in response to the reciprocation of the piston. A seal attached to the piston prohibits a fluid backflow between the external surface of the piston and the internal surface of the cylindrical guide. A bumper seal at the output end of the piston prevents fluid flow through the cylindrical guide when the solenoid coil is de-energized. A control circuit periodically energizes the solenoid coil at a frequency determined by a variable resistance responsive to predetermined operational parameters. In a preferred embodiment, the metering pump is a fuel control element for a heater and the variable resistance is a thermistor or similar type of temperature sensitive resistance, which controls the rate at which fuel is delivered to the heater.

Abstract:

A universal intermittent windshield wiper circuit adaptable to the windshield wiper mechanism of automotive vehicles is disclosed herein. The intermittent wiper circuit comprises an R-C timer circuit periodically energizing a three pole double throw relay. The internal interconnections of the relay switch contacts permit the intermittent windshield wiper circuit to be connected to the wiper mechanism of almost all domestically manufactured automotive vehicle as well as many vehicles manufactured overseas using only external connections. The circuit is equally adaptable to external and concealed wiper mechanism.

International Classification:

F04B 1704

US Classification:

137270

Abstract:

A check valve having a dual valve seat, a valve member, a retainer, and a valve spring. The dual valve seat has a cylindrical body having an axial bore therethrough. A conical valve seat is provided at one end of the axial bore and a flat valve seat is provided at the other end of the axial bore. A recess is provided in the face of the cylindrical body at the end having the conical valve seat to form a first retainer seat and an annular recess is provided about the flat valve seat to form a second retainer seat by inverting the valve seat, the check valve may accept either a stem valve member having a conical sealing surface or a flat valve member having a flat sealing surface. The embodiment of this check valve in an electromagnetic fluid pump permits it to have different operating characteristics depending on which valve member is used.

International Classification:

F04B 1704

US Classification:

417417

Abstract:

A high pressure fluid pump having a telescoping cylinder assembly disposed in a cylindrical sleeve. The telescoping cylinder assembly has a stationary member rigidly attached to the cylindrical sleeve and a telescoping member biased towards an outlet port. The telescoping member is reciprocated relative to the stationary member by the displacement of an armature in response to the intermittent energizing of a solenoid coil. An inlet valve connected to the telescoping member and an outlet valve connected to the stationary member provide a unidirectional fluid flow through the telescoping cylinder assembly with the reciprocation of the telescoping member. The outlet valve has a flat valve member which is biased against a valve seat provided at the end of the stationary member adjacent to the outlet port. The flat valve member is preferably made from a resilient elastomer which increases the efficiency of the pump and eliminates forward and back syphoning.

H02K 3302

US Classification:

417417

Abstract:

An electromagnetic fluid pump having a magnetic circuit responsive to a predetermined position of a reciprocating magnetically permeable piston is disclosed. The reciprocating piston closes the magnetic circuit at the end of its pumping stroke increasing the value of the signal produced by a hall effect switch. The increased value of the generated signal energizes a solenoid coil returning the piston to a cocked position against the force of a resilient member which urges the piston forward on its pumping stroke.
