Abstract: The invention provides a valve comprising a house (2) and a drum (3) rotatable in the house. The house comprises a plurality of substantial identical tubular mid-section house members (4), a bottom house member (5), and a top house member (6). When connecting the house members (4, 5, 6) to each other, a continuous outer wall surrounding a house cavity, a port (7), and a plurality of nozzles (8) being in fluid communication with the house cavity is provided. The drum comprises a plurality of substantial identical tubular mid-section drum members (9), a bottom drum member (10), and a top drum member (11). When connecting the drum members ((9, 10, 11) to each other, an inner wall having an outer surface (12) being adapted for rotation in contact with a corresponding inner surface (13) of the outer wall, the inner wall comprising a plurality of conduits (14) is provided. During rotation of the drum, the conduits can be brought into and out off fluid communication with the nozzles in order to provide passages between the port and the nozzles. Furthermore, the invention provides a set of members to form a valve, and a system for thermal exchange.

Abstract: An expansion valve (1) is described comprising a housing (2) having in inlet port (3) and an outlet port (4), a valve seat (5) arranged between the inlet port (3) and the outlet port (4), a valve element (6) movable over an operating stroke between a closed position at the valve seat (5) and an opened position away from the valve seat (5), and an actuator (7), wherein the actuator (7) comprises an electric rotary motor (8) acting on the valve element (5) by means of a threaded spindle (10) and a nut (9), wherein one of spindle (10) and nut (9) is rotatably driven by the motor (8) and the other one is rotatably fixed. Such an expansion valve should have the possibility for a simple assembly. To this end, in a disassembled condition of housing (2) and actuator (7) the actuator (7) has a mounting stroke which is at least two times the operating stroke, wherein the mounting stoke extends the operating stroke.

Abstract: A flow control valve (1) for a refrigeration system is disclosed. The valve (1) comprises a valve port (14) having a substantially cylindrical inner circumference arranged to receive a protruding portion of a valve member (5). The valve member (5) comprises a protruding portion having a substantially cylindrical outer circumference corresponding to the inner circumference of the valve port (14), said protruding portion also having at least one fluted part (16), said at least one fluted part (16) defining fluid passage along the at least one fluted part (16) when the valve member (5) is in the open position. The valve member (5) is provided with at least one first fluid passage (6) extending through the valve member (5) between a second valve chamber (15) and a pressure balancing chamber (8), and at least one second fluid passage (7) establishing a fluid connection between a first valve chamber (12) and the first fluid passage (6). The second fluid passage (7) has an opening arranged on the substantially cylindrical part of the protruding portion of the valve member (5). The invention allows the pressure of the balancing chamber (8) to be adjusted independently of the primary flow through the valve (1), via the fluted parts(s) (16).

Abstract: The present invention relates to a valve arrangement (2) for an operation mode selector of an air conditioning system, the valve arrangement (2) comprising a tube element (3) which comprises a discharge port (4), a suction port (5) and an evaporator port (6), the valve arrangement (2) furthermore comprising two or more mode selecting valves (9, 10) being arranged for selectively establishing a fluid connection through either the discharge port (4) or the suction port (5). It is the object of the invention to provide a compact design while still allowing silent switching between operation modes. The object is solved by one or more of the mode selecting valves being two-step opening valves. The invention furthermore relates to a pipe arrangement (1) comprising one or more of those valve arrangements (2) and an air conditioning system comprising such a valve arrangement (2) or such a pipe arrangement (1).

Abstract: An expansion valve (1) is disclosed which comprises an inlet opening (2), at least one outlet opening (3) and first and second valve parts. The inlet opening (2) is adapted to receive fluid medium in a liquid state. The outlet opening(s) (3) is/are adapted to deliver fluid medium in an at least partly gaseous state to a flow path. The valve parts are arranged movable relative to each other in such a manner that the mutual position of the first valve part and the second valve part determines a fluid flow between the inlet opening (2) and the outlet opening(s) (3). During normal operation, a resulting force acts upon the first valve part and/or the second valve part to press the first and second valve parts towards each other. The expansion valve (1) comprises means for reducing the resulting force acting upon the valve part(s). Thereby the valve parts can easier be moved relative to each other, and the force required in order to operate the valve (1) is thereby reduced.
