A linear drive, which has a housing ( ) delimiting a receptacle ( ), in which the drive means ( ) are arranged and from which the force or power transmitting member ( ) extends, which cooperates with the drive means ( ). The drive means ( ) are a component of an electrical linear motor ( ) which as a cartridge-like unit ( ) is inserted is into the receptacle and secured in place in relation to the housing.

Linear drive

A micro-valve arrangement whose micro-valve has a housing containing two opposite housing layers, between which a valve chamber is delimited, wherein a valve member is located. A fluid duct extending in one housing layer opens into the valve chamber and is controlled by the valve member. By means of an electrically operated actuator it is possible for the position of the valve member to be predetermined. Furthermore a position detector is present, which on the basis of the measured capacitance of a capacitor renders it possible to find the position of the valve member. This capacitor comprises two capacitor faces which are provided opposite to each other in the direction of motion of the valve member and on one of the housing layers.

Micro-valve with capacitor plate position detector

A set of independently usable linear drive, which include at least one fluid power and at least one electrical linear drive. The principal housing bodies of the linear drive are respectively provided with an elongated receiving space, in which fluid power drive means or electrical drive means are located dependent of the type of drive. As regards their outer shape the principal housing bodies at least essentially the same and their receiving spaces possesses the same cross sectional form. Accordingly on the basis of a large number of the identical component different types of linear drive may be produced.
