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: Electric expansion valve (1) including a valve housing (12), a valve seat (2), a valve element (3) cooperating with the valve seat (2), a drive driving the valve element (3) and including a rotary motor (4) having an axis (17) of rotation. The valve element (3) is connected to the motor (4) and has a possibility of radial displacement between the rotor (6) and the valve element (3) with respect to the axis (17) of rotation. Such an expansion valve should ensure a long lifetime with low production costs. To this end the valve element (3) is connected to the motor (4) by means of a fixing element (16) which guarantees a defined position of the valve element (3) in axial direction while allowing the radial displacement between the axis (17) of rotation and the valve element (3).
