Abstract
A thermostat housing assembly (10) presents a mounting face (22) including n outer seal (26) disposed in an outer seal groove (24) and an inner seal (32) disposed in an inner seal groove (30). The outer seal (26) includes a lip (38) extending radially inwardly to a distal end cantilevered over the annular wall for retaining the flow control valve (14) in the recess (28). A channel (42) extends radially between the seal grooves (24) and (30) for receiving each of a plurality of spokes (40). A shoulder (46) on each of the spokes (40) snaps over an undercut (44) in each of the channels (42).

A thermostat housing (12) assembly comprising;
- a housing (12) having a flange (16) for mounting said housing (12) on a support structure and a tubular spout (18) extending from said flange (16) and defining a passageway (20) extending from an opening in said spout (18) to an opening in said flange (16) for fluid to flow therethrough,
- said flange (16) presenting a mounting face (22) for engaging the support structure and an outer seal groove (24) therein,
- an outer seal (26) disposed in said outer seal groove (24) for sealing said flange (16) to the support structure, and
- said flange (16) having a recess (28) therein disposed radially inwardly of said outer seal groove (24) and having an annular wall extending downwardly to a bottom surrounding said passageway (20),
- said assembly characterized by said bottom having an inner seal groove (30) disposed therein and an inner seal (32) disposed in said inner seal groove (30) for sealing engagement with a flow control valve (14).
