Pressure Holding Directional Control Valve
View pageUS Patent:
57381429, Apr 14, 1998
Filed:
Aug 9, 1996
Appl. No.:
8/694559
Inventors:
Craig R. Eike - DeKalb IL
Guy T. Stoever - Naperville IL
Guy T. Stoever - Naperville IL
Assignee:
Case Corporation - Racine WI
International Classification:
F15B 13044
US Classification:
13759617
Abstract:
A 2-position, 3-way directional control valve is described which prevents reverse flow from an actuator port to a pressure port in one position. In the preferred embodiment described, the valve is solenoid actuated and is spring biased to a drain position, wherein an extension central to a spool assembly penetrates through a check valve seat and lifts a check valve ball from its seat to permit flow from an actuator port to a drain port. In the actuated or energized position, an armature assembly is shifted by a solenoid, drawing the spool assembly within the valve body and establishing a fluid path between a pressure port and the actuator port. In this position the extension of the spool assembly is withdrawn from the check valve seat. The check valve can be unseated by pressure from the pressure port to permit flow from the pressure port, through the spool and the check valve assembly. In the event of loss of pressure from the pressure port, such as due to shifting of other valves coupled to a pressure source, the check valve reseats to prevent reverse flow from the actuator port to the pressure port.
Brake Control System And Related Method

59042281, May 18, 1999
Filed:
Mar 3, 1997
Appl. No.:
8/808018
Inventors:
Craig R. Eike - DeKalb IL
Guy T. Stoever - Naperville IL
Guy T. Stoever - Naperville IL
Assignee:
Case Corporation - Racine WI
International Classification:
F16D65/24
US Classification:
188170
Abstract:
A simplified brake control system comprises a source of pressurized fluid, a spring-set brake with a hydraulic release mechanism and a control valve connected between the brake and the source. The control valve has a valve body and a flow control mechanism in the body and mounted for movement between a first (solenoid-energized) position and a second (solenoid-de-energized) position. A one-way check valve is built into the valve body. How the system operates depends upon two factors, namely, (a) whether the valve flow control mechanism is in its first or its second position, and (b) the relationship of the pressure of the source, i. e. , the first pressure, and the second pressure in the release mechanism. When the flow control mechanism is in the first position, the release mechanism may be pressurized for brake release. And when such mechanism is in the second position, the release mechanism is vented to the reservoir through the brake port, the second passage and the drain port.

International Classification:
G06G7/70
US Classification:
701 67
Abstract:
In a vehicle having a power shift transmission engageable in a plurality of forward gear ratios by engaging and disengaging first and second fluid clutches with a fluid from a fluid supply, a manifold apparatus for measuring a pressure of the fluid and simultaneously filling the first and second clutches with the fluid supply having a first clutch fill valve fluidly coupled to the first clutch to control the flow of the fluid to the first clutch; a second clutch fill valve fluidly coupled to the second clutch to control the flow of the fluid to the second clutch; a manifold fluidly coupled to the first and second clutch valves to conduct the fluid from the fluid supply to the first and second clutch valves; a first flow restrictor disposed between the manifold and the fluid supply to restrict the flow of the fluid from the fluid supply to the manifold; and a pressure transducer fluidly communicating with the manifold to generate a signal representative of the pressure of the fluid within the manifold, where the first and second clutches are not simultaneously engaged to provide any of the plurality of forward gear ratios.
Flow Restrictor Assembly In Transmission Clutch Control System
View pageUS Patent:
62058754, Mar 27, 2001
Filed:
Aug 31, 1999
Appl. No.:
9/386620
Inventors:
Craig Eike - DeKalb IL
Guy Thomas Stoever - Naperville IL
Guy Thomas Stoever - Naperville IL
Assignee:
Case Corporation - Racine WI
International Classification:
F16H61/04
US Classification:
74335
Abstract:
There is provided in accord with the present invention a work vehicle having a transmission and a clutch control system controlling the vehicle clutches, with the clutch control system including a flow restrictor assembly. The flow restrictor assembly comprises a modulator valve and an unloading valve in fluid communication with the fluid supply and the clutch control system. The unloading valve is selectively in fluid communication with the modulator valve through a modulator tank orifice and is responsive to fluid pressure changes acting on the modulator valve, as the clutch control system operates to control the length of time the modulator valve regulates the rate of flow of fluid to the clutch control system through the modulator tank orifice. In one embodiment the unloading valve spool is nested inside the modulator valve spool.

International Classification:
F16D 2500
F16D 1372
F16D 1372
US Classification:
192 85R
Abstract:
A work vehicle configured for selectively applying power to a load and comprising a frame, a plurality of ground support devices movably secured to the frame, an engine supported by the frame, a source of hydraulic fluid at a pressure, a clutch for selectively coupling the engine to the load in response to a control signal, the clutch including a clutch actuator configured for engaging the clutch upon receipt of an actuating fluid at least a first predetermined pressure, the clutch configured to dissipate heat of engagement to a flow of a lube fluid; and a clutch control valve located intermediate the fluid source and the clutch and disposed in the path of the actuating fluid and the lube fluid. The control valve is configured to control flow of the lube fluid to the clutch to a first predetermined rate while the clutch is not engaged, to control flow of the lube fluid to the clutch to a second predetermined rate at least for a predetermined length of time prior to engagement of the clutch, and to control flow of the actuating fluid at a predetermined pressure to the clutch actuator after the flow rate of the lube fluid has been increased.
