1. A thermostatic valve fitted with a housing which comprises at least two mutually apart coolant hookups, further with a thermally expansible device, comprising:
a housing; a push-rod attached to the housing and operating in concert with a valve element that in turn operates in concert with an annular valve seat, said valve seat being situated between the two hookups; and a spring that biases the valve element toward the valve seat, wherein the valve element is in the form of an annular valve disk made by two-part injection molding, where one annular sealing portion is made of an elastomeric plastic and the remaining valve disk is made of a hard plastic with an outer sealing portion cooperating with the valve seat and an inner sealing portion cooperating in a sealing manner with a housing of the thermally expansible device when said thermally expansible device is received in the aperture of the annular valve disk. |
