Filed:

Dec 19, 1990

Appl. No.:

7/629983

Inventors:

Gary C. Sutton - North Potomac MD

US Classification:

D10 59

US Patent:

46948589, Sep 22, 1987

Filed:

Aug 29, 1986

Appl. No.:

6/901684

Inventors:

Gary Sutton - Augusta GA

Assignee:

General Signal Corporation - Stamford CT
Dempster Systems, Inc. - Knoxville TN

International Classification:

F15B 1306

US Classification:

137596

Abstract:

A control valve having three motor passageways and a combination sequence and regeneration valve in a common housing, wherein the combination sequence and regeneration valve operates to prevent fluid communication between the third motor passageway and an inlet passageway when the pressure in the inlet passageway is below a first predetermined amount and permits bidirectional fluid communication between the third motor passageway and the inlet passageway when the pressure in the inlet passageway exceeds that predetermined amount.

US Classification:

414525R

Abstract:

A hydraulic control system is provided, including first and second bidirectional fluid actuated motors adapted to travel a predetermined amount in each direction. A directional control valve is placed in fluid communication with a supply of high pressure, hydraulic fluid and a reservoir and has a first operating position for directing the supply of fluid to the motors in a first direction of flow and a second operating position for directing the supply of fluid to the motors in a direction of flow opposite to the first direction of flow. A combination sequence and regeneration valve is in continuous fluid communication with the supply and the second motor for preventing the operation of the second motor until the first motor has reached its limit of travel and for regenerating fluid from one side of the second motor to the other side when the first motor has reached its limit of travel and the control valve is in its second operating position. The directional control valve and the combination sequence and regeneration valve are contained within a common housing having three motor passageways. The first two motor passageways cooperate with the directional control valve for providing bidirectional flow to the motors.
