Device for vertical adjustment of body of motor vehicle, has pump connected with retaining space i.e. cylindrical annular space, for retaining assigned to linear movably led support plate or linear movably led spring collar

摘要

The device (1) has a spring strut with a spring that is clamped between upper and lower spring collars. A control unit (7) includes a spatial pump (8) that is operated by a ball screw (10) driven by a motor (9). The pump is connected with a retaining space (12) i.e. cylindrical annular space (14), for retaining a hydraulic or pneumatic medium by a hydraulic or a pneumatic line (11), where the retaining space is assigned to a linear movably led support plate or linear movably led spring collar (5).
