Definitions
- a control valve assembly includes a valve body having a valve opening, a first pressure passage, a second pressure passage, and a valve body land.
- a valve member is received in the valve opening for movement between an open and a closed position.
- the valve member includes a first valve member land and a second valve member land.
- the first valve member land and the valve body land cooperate to define a first metering flow passage between the first and second pressure passages
- the valve body land and the second valve member land cooperate to define a second metering flow passage between the first and second pressure passages.
- the first and second metering flow passages are configured to impart a hydrodynamic force on the valve member during fluid flow through the valve body, which biases the valve member toward the open position or the closed position.
- FIG. 4A is an enlarged cross-sectional view of the control valve assembly of FIG. 2, showing the valve member in a closed position;
