Abstract: The invention relates to an axial valve comprising an actuator (15) and a center tube (19). The actuator comprises a stationary element (16) and a closing element (17), and the center tube (19) is placed axially in relation to an axial extension of the stationary element (16). The center tube (19) is in a fixed position relative to the stationary element (16). Fluid, such as refrigerant, is intended for flowing through the valve and through the center tube. The center tube (19) comprises orifices (22) for fluid passage. The closing element (17) is placed axially to an axial extension of the center tube (19) and is movable axially along the center tube between a first position, where the closing element closes the orifices (22) of the center tube, thereby not allowing fluid to pass the orifices, and a second position, where the orifices (22) are open, thereby allowing fluid to pass the orifices.

Abstract: A valve (1), in particular expansion valve, is described including a valve element (6) driven by a rotary motor (7), wherein the motor (7) includes a rotor (9) arranged inside a motor section (19) of a tube (14) and a stator (8) arranged outside the motor section (19) of the tube (14) and the rotor (9) is supported by a bearing (15), which bearing (15) is mounted with press fit in a bearing section (16) of the tube (14). Such a valve should have a small motor and a tube which can be produced with low costs. To this end the motor section (19) and the bearing section (17) include different diameters.

Abstract: The present invention pertains to a thermal expansion valve for a heat exchanger with at least one header. The valve includes a valve block and a superheat defining mechanism. The valve block includes a high pressure inlet, a low pressure outlet, a first suction gas port and a second suction gas port. A contact surface for coupling the valve to the header includes at least one cylindrical portion of the valve block. The invention is also directed at a heat exchanger with a corresponding thermal expansion valve.

Abstract: A linear actuator (1) comprising a first part (3) and a second part (5) is disclosed. The first part (3) is arranged to rotate along with a rotating part (4) of a motor (2), and the second part (5) is arranged to drive an actuated part (18, 22). A coupling (6) interconnects the first part (3) and the second part (5) to allow the second part (5) to rotate along with the first part (3) at the same angular velocity as the first part (3). The coupling (6) defines a fit tolerance between the first part (3) and the second part (5) allowing the first part (3) to rotate a predefined distance before engaging the second part (5) and rotating the second part (5) along with the first part (3). The fit tolerance ensures that the first part (3) reaches a certain angular velocity and thereby that the resulting torque transfer from the first part (3) to the second part (5) is sufficient, e.g. to release the actuated part (18, 22) from a pre-tensioned state.

Abstract: Valve (1), in particular expansion valve, is described including a valve element driven by an actuator and being arranged in a valve housing arrangement (4, 5, 15), wherein the valve housing arrangement (4, 5, 15) includes a housing (4), a tube (15) connected to the housing (4) and at least one connector (5) extending from the housing (4), wherein the actuator comprises a rotary motor having a stator and a rotor, the rotor being arranged inside the tube (15) and the stator being arranged outside the tube (15). A simple way is needed to position the stator and the rotor relative to each other. To this end the stator is fixed to a stator holder (16) which is arranged around the tube (15) and connected to the housing arrangement (4, 5, 15).
