1. A fluid valve, said valve comprising:
- (a) plastic housing means, said housing means including structure defining,(i) a fluid inlet,(ii) a fluid outlet,(iii) a fluid chamber communicating with said inlet and said outlet,(b) valve means disposed in said fluid chamber and movable between an open and closed position for valving fluid flow to said outlet in response to a varying condition;
(c) socket means formed of metal and received in an opening in the wall of said chamber, said socket means including;
(i) structure defining a heat accepting surface portion in contact with fluid flowing through said fluid chamber, said socket means defining a bore having heat transmitting surfaces therein,(ii) an annular recess having received therein a portion of the plastic material of said housing for preventing removal of said socket means;
(iii) locking surface means engaging said chamber wall and operable for preventing rotation of said socket means in said opening with respect to said wall;
(d) seal means operable to prevent fluid passage between said socket means and said housing means;
(e) temperature sensing means disposed at least partially in said bore and operatively receiving heat from said heat transmitting surfaces, said temperature sensing means being adapted for electrical connection to means for selective control thereof; and
(f) said valve means including a valve member spaced closely adjacent said heat accepting surface portion, said valve member including a fluid deflecting surface portion operable when said valve means is in said open position to deflect a portion of the flow through said chamber to create a vortex for effecting rapid heat transfer between the fluid and said socket means.

Abstract
A water valve is disclosed for use in passenger vehicle heating systems. The valve includes a cylindrical metallic socket having a heat accepting surface portion connected to the valve housing and in fluid communication with fluid flowing through the valve. The position of the heat accepting surface portion relative to a rotatable butterfly valve member results in a vortex flow condition across the face of the heat accepting surface portion, thereby providing fast heat transfer from the fluid to the socket.

7. A fluid valve comprising:
-
(a) housing means formed of plastic material and including structure defining, (i) a fluid inlet, (ii) a fluid outlet, (iii) a fluid chamber communicating with said inlet and said outlet, (b) valve means disposed in said fluid chamber and movable between an opened and closed position for valving flow to said outlet in response to a varying condition; (c) socket means formed of metal and received through the wall of said chamber, said socket means including, (i) structure defining a heat accepting surface portion in contact with fluid flowing through said fluid chamber, said socket means defining a bore having heat transmitting surfaces, (ii) an annular recess having disposed about the outer periphery received therein a portion of the plastic material of said housing for preventing removal of said socket means, (iii) locking surface means engaging said chamber wall and operable to co-act therewith for preventing rotation of said socket means with respect to said wall; and
,(d) seal means operably disposed to prevent fluid passage between said socket means and said housing means; and
,(e) temperature sensing disposed at least partially in said bore and operatively receiving heat from said heat transmitting surfaces, said temperature sensing means being adapted for electrical connection to means for selective control thereof.
