Abstract
A thermostatic control valve for regulating the supply of fluid through a conduit includes in combination a valve plate and seat in the conduit, the valve plate having a valve stem extending outwards of the conduit with the valve stem having a spring exterior of the conduit to move the plate away from the seat and a housing secured to the conduit with a retractable plunger in the housing operative on the valve stem. The plunger is contained in a casing having means responsive to temperature change to move the plunger towards the seat. An interior member is threaded in the housing and removable means are used for attachment to the interior member to rotate it in the housing, thus providing adjustment. The control valve is secured to the conduit through a washer having a pawl which engages with ratchet shaped teeth of a ring secured in the control valve.
