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
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.

[ What is claimed is:] [1.] Valve for a system having an energy-carrying medium which flows through a number of energy exchangers (5) in the system, said valve (8) having a thermostat valve (12) with a housing (9) comprising an inlet (15) and an outlet (16), a spindle (42) which can be displaced by
[ What is claimed is:] [1.] Valve for a system having an energy-carrying medium which flows through a number of energy exchangers (5) in the system, said valve (8) having a thermostat valve (12) with a housing (9) comprising an inlet (15) and an outlet (16), a spindle (42) which can be displaced by a thermostat bellows and having a seal (32), and which depending on the expansion/contraction of the thermostat bellows and against the pressure of a spring (43) which surrounds the spindle (42) can respectively close and open an opening (28) with a seating (28a) in a transverse wall (29) in the housing (9) between the inlet (15) and the outlet (16), where the valve (8) also has a differential pressure controlled membrane (17, 21) for the regulation of the differential pressure of the energy-carrying medium across an adjustable pre-setting (11) and the thermostat valve (12) consisting of the seating (28a) and the seal (32) between the inlet (15) and the membrane (17, 21), and that the thermostat valve (12) is arranged to be able to cut off the flow between the inlet (15) and the outlet (16) independently of the adjustable pre-setting (11), and the membrane (17) of the differential pressure valve (10) is placed in a first bush (18) which is disposed in the housing (9) and suspended coaxially around the axis (19) of same, that a spring (25) is provided between the membrane (17) and the bottom of the first bush (18), that a first channel (26) from the inlet (15) leads to the upper side of the membrane (17), that at least one second channel (30) leads from the opening (28) to the underside of the membrane (17), which is arranged to be able to roll in over slots (22) in the first bush (18) for at least a partial closing of the slots (22), and in that the housing (9) opposite the slots (22) has an annular recess (23) which is open towards the outlet (16), an improvement, comprising:the valve wherein the housing (9), and suspended coaxially around the axis (19) of same, the adjustable pre-setting (11) comprises a cup-shaped bush (41), the mouth of which has an edge which is cut off in such a manner that a remaining half (41a) can extend beyond the inlet (15) in a given turned position of the cup-shaped bush (41).
