Abstract

A valve system (18) includes an actuator (38) that selectively drives a valve member (42) between a first position and a second position to control fluid flow to an outlet port (34) and a bypass port (36). A temperature sensor (19) indicates a fluid temperature to a controller (21), which controls the actuator (38) to control the position of the valve member (42) based upon the fluid temperature. A bias feature (41a, 41b) biases the valve member (42) toward one of the first position or the second position in response to an inoperable state of the actuator (38).

Claims

AMENDED CLAIMS received by the International Bureau on 28 July 2006 (28.07.06) original claims 1-21, replaced by amended claims 1-21 (3 pages).
1. A valve system comprising: an actuator; a valve member driven by the actuator and selectively moveable between a first position and a second position to control flow through a plurality of passages; and a bias feature having oppositely located surfaces of unequal area that induce a pressure differential on the valve member in response to coolant flow against the valve member to bias the valve member toward one of the first position or the second position in response to an inoperable state of the actuator.
2. The valve system as recited in Claim 1, wherein the oppositely located surfaces are substantially semi-circular.
3. The valve system as recited in Claim 2, wherein the valve member comprises a disk.
4. The valve system as recited in Claim 1, wherein the valve member includes an inlet port, and at least one of the plurality of passages comprises a bypass port having an end portion that extends at least partially into the inlet port.
5. The valve system as recited in Claim 4, wherein the valve member seals against the end portion of the bypass port in one of the first position or the second position to prevent flow into the bypass port.
6. The valve system as recited in Claim 4, wherein the bypass port is substantially perpendicular to the inlet port.
7. The valve system as recited in Claim 1, wherein the valve member includes a first surface that generally faces in a flow-receiving direction and a second surface that faces in an opposite direction.
8. The valve system as recited in Claim 7, wherein the first surface seals against a first valve seat within one of the plurality of passages and the second surface seals against a second valve seat within the one of the plurality of passages when in the first position.
9. The valve system as recited in Claim 8, wherein the first valve seat includes a first seal surface that faces in a first direction and the second valve seat includes a second seal surface that faces in a second direction that is opposite of the first direction.
10. The valve system as recited in Claim 8, wherein the valve member comprises an axle in driving communication with the actuator, and each of the first valve seat and the second valve seat seal against the axle.
11. The valve system as recited in Claim 8, wherein the first valve seat defines a first plane and the second valve seat defines a second plane that is non-planar with the first plane.
12. The valve system as recited in Claim 11, wherein the valve member defines a valve member plane that is non-planar with each of the first plane and the second plane.
13. The valve system as recited in Claim 8, wherein the first surface seals against an end portion of another of the plurality of passages when in the second position.
14. A method of controlling the valve system as recited in claim 1, comprising the steps of: inducing a pressure differential on the valve member in response to coolant flow against the valve member; and moving the valve member with the pressure differential toward one of the first position or the second position in response to an inoperable state of an actuator.
15. The method as recited in Claim 14, including the step of generating a pressure differential on the valve member in response to coolant flow against the valve member to bias the valve member toward the one of the first position or the second position.
16. The method as recited in Claim 14, including the step of pivoting the valve member about an axis that extends through the valve member in response to the pressure differential.
17. The method as recited in Claim 15, wherein the first position allows coolant to flow to a heat exchanger and the second position allows coolant to bypass the heat exchanger, and the method includes the step of biasing the valve member to the first position.
18. The method as recited in Claim 17, including the step of sealing the valve member against a first seal surface in the first position and against a pair of oppositely-facing seal surfaces in the second position.
19. A coolant system comprising: a heat exchanger; a combustion engine; a coolant loop that fluidly connects the heat exchanger and the combustion engine; and a bypass valve within the coolant loop, the bypass valve comprising: an actuator; a valve member driven by the actuator and selectively moveable between a first position that allows fluid flow to bypass the heat exchanger and a second position that allows fluid flow to the heat exchanger; and a bias feature having oppositely located surfaces of unequal area that induce a pressure differential on the valve member in response to coolant flow against the valve member to bias the valve member toward the second position in response to an inoperable state of the actuator.
