摘要

The invention relates to a device for the remote adjustment of components which can be moved relative to one another, in particular components of toys, teaching aids or the like, using working cylinders, which can be pressurised by a - preferably liquid - pressure medium, and a pressure pump connected to the said cylinders by conduits. In this device, the working cylinders each comprise two hollow cylindrical housing parts which can be moved telescopically and easily relative to one another, are provided at the ends with connection means, are open at one end and in the interior of which is arranged a bellows, the ends of which are connected to in each case one end face of the two hollow cylindrical housing parts and which has at least one inlet and outlet port leading out of the housing for the pressure medium. The device also includes a connecting conduit for the pressure medium, in which a preferably motor-driven pump with a reversible direction of delivery is arranged between a reservoir and the working cylinder(s).
