First Claim
Patent Images
1. A mixing valve comprising:
- an inlet;
a flow control valve comprising a valve member assembly comprising a first valve member coupled to a second valve member, wherein the first and second valve members are spaced apart from each other and are configured to seal two separate outlets when the flow control valve is in a closed position;
a stepper motor configured to simultaneously move the first and second valve members to selectively seal or unseal the two separate outlets.

Abstract
A mixing valve includes an inlet and a flow control valve that includes a valve member assembly having a first valve member coupled to a second valve member. The first and second valve members are spaced apart from each other and are configured to seal two separate outlets when the flow control valve is in a closed position. The mixing valve also includes a stepper motor configured to simultaneously move the first and second valve members to selectively seal or unseal the two separate outlets.

11. A mixing valve comprising:
-
a flow control valve comprising a spool, a first valve member, and a second valve member, wherein the first and second valve members are coupled to the spool and spaced apart from each other, and wherein the first and second valve members are each configured to engage a separate valve seat when the flow control valve is in a closed position so as to each seal a separate outlet into a mixing chamber; and a stepper motor coupled to the spool and configured to simultaneously move the first and second valve members. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A mixing valve comprising:
-
a first inlet for introducing a first fluid into a first valve chamber; a second inlet for introducing a second fluid into a second valve chamber; a mixing chamber configured to receive the first and second fluids from the first and second outlets; a first valve member assembly associated with the first inlet; a second valve member assembly associated with the second inlet; a first stepper motor configured to move the first valve member assembly; and a second stepper motor configured to move the second valve member assembly; wherein each of the first and second valve member assemblies comprises two spaced-apart valve members configured to simultaneously open or close two separate outlets into the mixing chamber. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
