Piston-cylinder assembly
The invention relates to a piston-cylinder assembly (1) comprising a cylinder housing (3), in which a main piston (2) and at least one dragg piston (11, 12) are axially slidably accommodated. The mainpiston (2) divides a piston chamber (7) of the cylinder housing (3) into two pressure chambers (8, 9...

Zusammenfassung: | The invention relates to a piston-cylinder assembly (1) comprising a cylinder housing (3), in which a main piston (2) and at least one dragg piston (11, 12) are axially slidably accommodated. The mainpiston (2) divides a piston chamber (7) of the cylinder housing (3) into two pressure chambers (8, 9) having variable volume, by means of which pressure chambers a pressure fluid can be applied to the main piston (2) on both sides and to the at least one drag piston (11, 12) on one side. The drag piston (11, 12) is axially slidably guided on a cylindrical outer lateral surface (38) of the main piston (2), which outer lateral surface extends laterally to a circular piston flange (10), which acts as an axial abutment and which points radially outward. The drag piston (11, 12) has, on the end thereof near the piston flange, a pushing portion (13, 14), which extends axially inward with respect to the piston flange (10). A displacement limiter (28) for limiting the displacement of the drag piston (11, 12) is arranged |
