<p>A valve for a pipe system wherein liquid circulates is intended to be controlled dependent on the liquid temperature within the system by means of a thermostat adapted to actuate an electro magnet which, on its part, dependent on whether it is current-carrying or not, is adapted to retain the valve spindle (2) in a position corresponding to open or closed valve position, respectively. The valve housing (1) has a plate-shaped seat body (5) having a large central through-going flow opening (6) and a number of smaller corresponding openings (7) closer to the circumference. A spring-loaded (12) first valve body (10) is displaceably arranged on the spindle (2) and cooperates with the central opening (6) of the seat body (5) in order to close/open said opening, a concentrical, spring-loaded (13) hollow piece constituting a second valve body (11) which also is displaceably arranged on the spindle (2), cooperating with said peripheric openings (7) via an annular flange portion (11') in order to close/open the last-mentioned openings. The two valve bodies (10, 11) are axially displaceable in relation to each other, and they are each assigned a carrier (14, 15) on the spindle (2).</p> |
