Embodiment Construction

[0018] Referring now to the drawings, in which like numerals are used to denote like structures, unless otherwise indicated, a control valve 10 for controlling the flow of a fluid medium is generally in Figure 1A and Figure 1B shown in . It should be understood that the control valve 10 may be a pressure control valve 10 or a flow control valve 10. Additionally, control valve 10 may include one or more of any type of valve used to regulate a fluid medium, including check valves, poppet valves, ball valves, slide valves, and the like. Additionally, the control valve 10 may be actuated by any linear force including solenoids, power screws, hydraulic actuators, pneumatic actuators, and the like.

[0019] see still Figure 1A and Figure 1B , the control valve 10 defines a plurality of ports and defines a fluid passage 12 between one or more of these ports. exist Figure 1A In the illustrated embodiment, the control valve 10 defines a supply port 14 configured to allow fluid ...

Abstract

A control valve for controlling a flow of fluid medium includes a push rod extending along an axis and configured for movement between an unactuated position and an actuated position. The control valve also includes a valve member operably coupled to the push rod for controlling the flow of fluid medium. Additionally, the control valve includes a valve body having an interior surface defining a fluid passage. The valve body includes a push rod guide concentric with said fluid passage. The push rod guide is also disposed about said push rod along said axis for guiding said push rod between saidunactuated position and said actuated position. The valve body also includes a push rod guide support disposed within said fluid passage. Finally, the push rod guide support is integral with and extends between said interior surface of said valve body and said push rod guide.

Description

technical field [0001] The present invention relates generally to hydraulic control solenoids, and more particularly to a control valve for use in hydraulic control solenoids. Background technique [0002] Conventional vehicle powertrains known in the art generally include an engine in rotational communication with a transmission. The engine produces rotational torque that is selectively translated to a transmission, which in turn translates rotational torque to one or more wheels. A typical transmission shifts in discrete steps between a high-torque, low-speed mode for launching the vehicle and a high-speed, low-torque mode for running the vehicle at high speeds. In a manual transmission, shifting is accomplished by manually controlled engagement of the gear sets. In an automatic transmission, gear shifting is achieved by the automatically controlled engagement of friction elements. [0003] To facilitate shifting and controlled engagement of friction elements of an auto...
