摘要

The pistol gun has a valve insert (10) and lever device (11) for biasing the operating pin (24) of the vehicle. The operating pin is biased by the lever device in a first operating section with greater force and small stroke and in a following second operating section with lower force and greater stroke. The lever device has at least two levers (29, 36) with different length active lever arms so that the first lever operates in the first operating section and the second lever in the second section.
