Title: Temp. responsive valve for water heating system
IPC: F16K21/04
Filed: 1983-04-05
Abstract: EP--92333 A The temp. responsive valve is provided for closing a fluid circulating loop in a thermo-syphon water heating system, e.g. including a solar panel. The valve (1) includes primary (4) and secondary (5) inlet ports, both communicating with an internal chamber (3). An outlet port (6) communicates with the chamber via an orifice (7) controllable by a valve member (14). - A temp. responsive probe (15) is connected to the valve member and functions to close communication between the inlet ports and the outlet port in response to fluid temp. A deflector (10) blocks direct access between the secondary inlet port (5) and the outlet port and induces the fluid entering this inlet port to flow in a direction towards the primary inlet port (4).

(17pp Dwg.No.1/6) - EP--92333 B A temperature responsive valve including, a hollow body (2), a chamber (3) defined within said body (2), a primary inlet port (4) and a secondary inlet port (5), each communicating with said chamber (3) so as to be in continual communication with one another, an orifice (7) within said body (2), an outlet port (6) communicating with said chamber (3) through said orifice (7), a valve member (14) mounted within said body (2) for movement towards and away from a position at which it closes said orifice (7), and temp. responsive means (15) located within or adjacent said primary inlet port (4) and being connected to said valve member (14) so as to control said movement thereof; characterized in that deflector means (10) is provided within said valve body (2) to influence the flow of fluid entering the valve through said secondary inlet port (5) so that it is directed away from said outlet port (6) and towards said primary inlet port (4). (11pp) USAB- US4492219 A A primary and a secondary inlet communicate with one another through a chamber within the valve body and communicate with an outlet through an orifice controlled by a valve member. A temp. responsive device is mounted within the primary inlet and is connected to the valve member so as to move that member into an orifice closing position when the temp. of fluid entering the inlet exceeds a predetermined value. - A deflector located within the valve body functions to influence the flow of fluid entering the valve through the secondary inlet so that it is directed away from the outlet and towards the primary inlet.
