ABSTRACT:
A valve of the type for controlling engine coolant flow to a heater core having a resilient butterfly valve formed of thermoplastic elastomeric material. The outer periphery is sufficiently resilient to absorb actuator overtravel in the seated condition. The butterfly has formed integrally therewith a central hub with torque-transmitting surfaces molded therein and a pair of oppositely disposed stiffeners extend outwardly from the hub in the central region of the butterfly. Assembly is simplified by placing the butterfly in the body and inserting a winged actuator shaft through journal holes in the body into the butterfly hub such that the wings on the shaft engage the torque-transmitting surfaces in the hub.
