| 摘要 |
The invention regards a floor spring (1), comprising a housing (2), a first piston (3), a second piston (4), and a spindle (5) extending through an opening (7) of the housing (2), wherein the spindle (5) is connected to the first piston (3) i.e. between the cam surface (6) and the main roller (17)such that a longitudinal movement of the first piston (3) is translated into a rotational movement of the spindle (5) under the effect of the loaded closer spring (8), and wherein the first piston (3) and the second piston (4) are formed integrally as a hybrid piston (9). |
