US Patent:

52901556, Mar 1, 1994

Filed:

Jul 24, 1992

Appl. No.:

7/919201

Inventors:

Douglas G. Snow - Walled Lake MI
Jerry L. Wilson - Farmington MI

Assignee:

Deco-Grand, Inc. - Royal Oak MI

International Classification:

F01C 2100

US Classification:

418 82

Abstract:

The balanced vane hydraulic pump designed for automotive power steering applications employs a two-piece aluminum housing construction, a cam ring, rotor flow regulating valve, a high pressure gallery, and a pressure plate, all located in the rear housing section, and a set of needle bearings located in the front housing section for supporting the pump drive shaft from one end only. The pressure plate has a sculpted portion which communicates with the cam ring side of the pressure plate. The sculpted portion is a wishbone-shaped gallery and a low pressure area, recessed within the face of the pressure plate. The pressure plate also includes high pressure windows which deliver high pressure fluid from the cartridge to the high pressure gallery located within the rear portion of the pump housing. An important feature of the pressure plate is that it uses hydraulically balanced low pressure and high pressure passageways which are contoured to efficiently direct the moving fluid within the pump which aides in minimizing the loss of energy within the pump's passageways. The front housing member, rear housing member and also the pressure plate, all employ a common symmetrical wishbone-shaped gallery as a low pressure fluid passageway which causes balanced low pressure hydraulic fluid to be delivered to two pairs of two diametrically opposed inlet windows adjacent to the low pressure inlet sectors of the cam ring.

Appl. No.:

7/659436

Inventors:

Jerry D. Wilson - Carrier Mills IL

International Classification:

A47G 900

US Classification:

5417

Abstract:

An inflatable stabilizer for use with a beach blanket or beach towel to prevent sand or dirt from getting on the blanket or towel, has an inflatable tube that is attached to the blanket or towel. The tube is a generally continuous tube and secured to the blanket or the towel provides a generally rigid peripheral edge that resists being buried in the sand or blown about on windy days.

US Classification:

Abstract:

A balanced vane hydraulic pump designed for automotive power steering applications employs a multi-vane rotor and cam ring. The pump has a three-piece aluminum housing construction, with the flow regulating valve located in the rear housing section, the cam ring and rotor located in the center housing section, and a two bearing sets located in the front housing section for supporting the pump drive shaft from one end only. The rear housing section also preferably includes a semi-flexible inner wall which under high pressure conditions bows inwardly toward the cam ring, rotor and vanes, thereby helping to maintain operating clearances so as to relatively help control leakage under varying pump output pressures, even though separate pressure and thrust plates are not used. An important feature of the pump is the use of hydraulically balanced low pressure and high pressure passageways which are contoured to efficiently direct the moving fluid and to minimize energy loss within the pump passageways, which enhances speed capabilities. The low pressure fluid passageways are in particular balanced through the use of a generally symmetrical wishbone gallery in the center housing section which feeds low pressure hydraulic fluid to two pairs of two diametrically opposed inlet windows adjacent to the low pressure inlet sectors of the cam ring.
