摘要： A method to manufacture a valve using metal injection moulding is disclosed. The valve housing comprises a welding cap for welding the upper part of the valve to the valve housing. The welding cap is placed so the upper part can be welding to the housing without damaging the inner cavity of the housing. There is a gab between the welding cap and the inner liner so the heat from the welding to not damage the inner liner allowing the inner parts of the valve to move freely.

摘要： 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.

摘要： In an expansion valve a valve body combines an inlet and outlet in an orifice in fluid communication therewith. A closure is positioned in the valve body and is movable between an opened and closed position to allow or prevent fluid to flow through the orifice from the inlet to the outlet. The valve body defines a bypass flow path which is in fluid communication with the outlet and inlet to allow fluid to flow from the outlet to the inlet, a bypass closure positioned in the bypass flow path is movable between an opened position and a closed position so that when said closures in said closed position fluid flowing from said outlet towards an inlet causes a bypass closure to move toward said opened position allowing fluid to flow on a reverse direction from the outlet to the inlet. When the closure moves toward the opened position fluid pressure maintains the bypass closure in the dosed position allowing fluid to flow from the inlet to the outlet. The bypass closure is free floating within the valve body.

摘要： A thermal expansion valve body for a thermal expansion valve. In order to provide universality so that the thermal expansion valve can ultimately be formed with an inlet and outlet either being aligned or at an angle to one another, the thermal expansion valve body includes an inlet protrusion for the inlet an outlet protrusion for the outlet, and a bypass aperture protrusion for a bypass aperture. The outlet protrusion and the bypass protrusion are substantially identical such that the outlet can be formed in one the outlet and bypass protrusions, and the bypass aperture can be formed in the other of the outlet and bypass protrusions.

摘要： 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).

摘要： The invention provides a servo valve which is operable in vacuum systems and can be switched between an open and a closed state even by use of low forces. For that purpose, the valve has a closure member (4) moving between the open and a closed position under influence of a difference between a control pressure of a control chamber (13) and the pressures of the intake (2) and outlet (3), respectively. The control chamber is in constant fluid communication with the intake, and in adjustable fluid communication with the outlet to influence the control pressure mainly by the intake pressure and the outlet pressure depending on the adjustable fluid communication. The invention further provides a vacuum system with such a servo valve.

摘要： The invention provides a solenoid actuated valve with a plunger which moves in a sleeve under influence of a magnetic field from the solenoid and further comprising a damping device for reducing noise and wear caused by the plunger when it bounces against a top part located in the sleeve. The damping device comprises a first part which forms the limit of the travel of the plunger and another part which is allowed to move relative to the first part in a dampened movement. To enable application in a vacuum system, the damping device comprises a conduit which allows evacuation of a chamber confined between one end of the sleeve and the damping device. The invention further provides a damper for a solenoid actuated valve.
