Abstract

A valve assembly includes an electronics housing and a valve housing assembly engaged to the electronics housing. The valve housing assembly includes a valve body defining a plurality of fluid ports in fluid communication with the valve bore. A plurality of fluid dampeners is disposed in the fluid ports. A sensor plate is engaged to the valve body. The sensor plate defines a plurality of sensor ports that are generally aligned with the fluid ports of the valve body. At least four fluid sensors are disposed in the plurality of fluid ports of the valve body. A cover is engaged to the sensor plate. The cover defines a cavity. A circuit board is disposed in the cavity of the cover. The circuit board is in electrical communication with the fluid sensors.

First claim

What is claimed is:

1. A valve assembly comprising:
a valve housing assembly having a valve body defining a valve bore and a sensor port in fluid communication with the valve bore;
a fluid sensor disposed in the sensor port;
a fluid dampener disposed adjacent to the fluid sensor, the fluid dampener including a first axial end and an oppositely disposed second axial end, the fluid dampener defines a recess having an opening in the first axial end, the second axial end defines an orifice that extends through the second axial end into the recess, wherein the orifice is at an oblique angle relative to a central longitudinal axis of the fluid dampener.

2. The valve assembly of claim 1 , wherein the fluid dampener is threadedly engaged to the valve body.

3. The valve assembly of claim 1 , wherein the fluid dampener is threadedly engaged to a fluid port defined by the valve body of the valve housing assembly, the fluid port being in fluid communication with the valve bore and the sensor port.

4. The valve assembly of claim 3 , wherein the valve body defines at least four fluid ports.

5. The valve assembly of claim 4 , wherein the valve body defines at least four sensor ports.

6. The valve assembly of claim 5 , wherein the valve housing assembly includes at least four fluid sensors.

7. The valve assembly of claim 1 , wherein the fluid sensor is adapted to sense pressure of fluid.

8. A valve assembly comprising:
a valve housing assembly defining a valve bore, a fluid port in fluid communication with the valve bore and a sensor port in fluid communication with the fluid port;
a fluid sensor disposed in the sensor port;
a fluid dampener disposed in the fluid port, the fluid dampener including a first axial end and an oppositely disposed second axial end, the fluid dampener defines a recess having an opening in the first axial end, the second axial end defines an orifice that extends through the second axial end into the recess, wherein the orifice of the fluid dampener is at an oblique angle relative to a central longitudinal axis of the fluid dampener.

9. The valve assembly of claim 8 , wherein the fluid dampener is threadedly engaged to the fluid port.

10. The valve assembly of claim 8 , wherein the valve housing assembly defines at least four fluid ports.

11. The valve assembly of claim 10 , wherein the valve housing assembly defines at least four sensor ports.

12. The valve assembly of claim 11 , wherein the valve housing assembly includes at least four fluid sensors.

13. The valve assembly of claim 8 , wherein the fluid sensor is adapted to sense pressure of fluid.

14. A valve assembly comprising:
an electronics housing;
a valve housing assembly engaged to the electronics housing, the valve housing assembly including:
a valve body defining a valve bore and a sensor port in fluid communication with the valve bore;
a fluid sensor disposed in the sensor port;
a fluid dampener disposed adjacent to the fluid sensor, the fluid dampener including a first axial end and an oppositely disposed second axial end, the fluid dampener defines a recess having an opening in the first axial end, the second axial end defines an orifice that extends through the second axial end into the recess, wherein the orifice is at an oblique angle relative to a central longitudinal axis of the fluid dampener; and
a circuit board being in electrical communication with the fluid sensor.

15. The valve assembly of claim 14 , wherein the fluid sensor is adapted to sense pressure of fluid.

16. The valve assembly of claim 14 , further comprising a conduit connecting the electronics housing and the valve housing assembly, the conduit having a first axial end and an oppositely disposed second axial end, the first axial end being engaged with the valve housing assembly, the second axial end being engaged with the electronics housing, the conduit providing a passageway from the valve housing assembly to the electronics housing.

17. The valve assembly of claim 16 , wherein a spring biases the conduit outwardly from the valve housing assembly.
