ABSTRACT:
Energy exchanger, valve (8) with thermostat valve (12), a housing (9) with inlet (15) and outlet (16), a thermostat bellows displaceable spindle (42) with a seal (32) which, against the pressure of a spring (43) surrounding the spindle (42), closes/opens an opening (28) in a transverse wall (29) in the housing (9) between the inlet (15) and the outlet (16), and a membrane (17, 21) controlled by the differential pressure for the control of an energy-carrying medium between the inlet (15) and the outlet (16), and an adjustable closing element (11) between the inlet (15) and the membrane (17, 21), the thermostat valve (12) being able to shut off the flow between the inlet (15) and the outlet (16) independently of the closing element (11). With the valve (8), only a predetermined maximum amount of the medium flows through the energy exchangers (5). If the differential pressure increases upon the closing of one or more valves on a pipe length, the flow in the individual energy exchanger (5) is not increased.
