ABSTRACT:
A thermostat housing assembly including a base member having a hollow tubular portion with a longitudinal axis and a first end opening disposed substantially on the axis and a second end opening offset from the axis at a predetermined angle, and an intermediate member including a cylindrical body portion and a first end portion in mating engagement with and connected to the second opening so that the intermediate member is disposed at the predetermined angle in relation to the longitudinal axis of the base member. Said intermediate member further includes a second end portion. A top stack member includes a hollow cylindrical portion having a port therethrough between the ends thereof and a cylindrical extension secured about the port. The top stack member further includes a first tapered end portion seated within and connected to the second end portion of the intermediate member so that the cylindrical end portion extends from the top stack member at a second predetermined angle in relation to the axis of the base member.
The instant invention further provides a method of manufacturing the thermostat housing including the steps of seating the first end portion of the intermediate member within the second opening of the base member to dispose the intermediate member at a predetermined angle relative to the longitudinal axis of the base member and seating the tapered end portion of the top stack member within the second end portion of the intermediate member to dispose the cylindrical extension of the top stack member at a second predetermined angle in relation to the longitudinal axis of the base member and securing the members together.
