Abstract

A valve including a valve body having at least two inlets and an outlet configured to be in fluid communication with the at least two inlets; an adjusting portion associated with the valve body, the adjusting portion providing a stop structure; a piston in fluid communication with the at least two inlets and the outlet; a thermostatic element configured to assist with moving the piston in response to engaging with the stop structure, the piston being configured to regulate fluid flow from the at least two inlets to the outlet; and a return spring configured to assist with biasing the thermostatic element; and a mixing part provides assistance with mixing fluid from the at least two inlets to the outlet, wherein the mixing part is integrally formed with valve body.

Claims (30)

1 . A valve including:

a valve body having:

at least two inlets; and

an outlet configured to be in fluid communication with the at least two inlets;

an adjusting portion associated with the valve body, the adjusting portion providing a stop structure;

a piston in fluid communication with the at least two inlets and the outlet;

a thermostatic element configured to assist with moving the piston in response to engaging with the stop structure, the piston being configured to regulate fluid flow from the at least two inlets to the outlet; and

a return spring configured to assist with biasing the thermostatic element; and

a mixing part provides assistance with mixing fluid from the at least two inlets to the outlet,

wherein the mixing part is integrally formed with valve body; and

the at least two inlets transition from a substantially circular shape to a substantially rectangular shape.

2 . The valve of claim 1 , wherein the return spring has a length that extends beyond one end of the mixing part.

3 . The valve of claim 1 , wherein the mixing part forms a channel with the valve body to receive the return spring.

4 . The valve of claim 1 , wherein one end of the mixing part is in the form of a free end.

5 . The valve of claim 4 , wherein the free end is at an opposite end to where the mixing part is connected to the valve body.

6 . The valve of claim 1 , wherein the mixing part includes a tube portion that extends from a connection with the valve body in a direction away from the outlet.

7 . The valve of claim 1 , wherein a ratio of piston height to piston diameter is in the range of 1:1.65 to 1:5.

8 . The valve of claim 1 , wherein a diameter of one of the at least two inlets is greater than the piston height.

9 . The valve of claim 1 , wherein the piston includes a spring seat that receives a force from the return spring that is configured to assist in biasing the thermostatic element.

10 . The valve of claim 1 , wherein one of the at least two inlets is a cold inlet and another of the at least two inlets is a hot inlet such that the cold inlet is aligned along an axis with the hot inlet, the axis extending across the piston.

11 . A method of manufacturing a valve, the method including the steps of:

forming at least two inlets in a valve body;

forming an outlet in the valve body; and

forming a mixing part in the valve body, the mixing part configured to assist with mixing fluid from the at least two inlets to the outlet;

wherein the mixing part is integrally formed with the valve body; and

wherein the at least two inlets transition from a substantially circular shape to a substantially rectangular shape.

12 . The method of claim 11 , wherein the step of forming the mixing part includes forming a channel in the valve body that is configured to receive a return spring and defines part of the mixing part.

13 . The method of claim 12 , wherein the method includes placing the return spring into the channel in a manner that allows its length to extend beyond one end of the mixing part.

14 . The method of claim 11 , wherein the method further includes inserting a thermostatic element into the mixing part.

15 . The method of claim 11 , wherein one of the at least two inlets is a cold inlet and another of the at least two inlets is a hot inlet such that the cold inlet is aligned along an axis with the hot inlet, the axis extending across the piston.
