A compressed gas motor and methods comprise a working plunger and a control plunger arranged in the internal space between the working plunger and a closed rear side such as to be mobile in linear direction. The control plunger, in a first position, covers a gas outlet opening and does not cover the gas inlet opening and, in a second position, covers the gas inlet opening and does not cover the gas outlet opening. The control plunger is supported as in a bearing such as to be mobile with respect to the working plunger, and a catch element is arranged on said working plunger and/or control plunger and pulls the control plunger in the direction of the working plunger, at a first distance, when the working plunger moves away from the control plunger, as well as a lavage system comprising said compressed gas motor. |

1. A compressed gas motor comprising a working plunger, an internal space that is closed on a rear side and has the working plunger arranged such that the working plunger is mobile in linear direction, a restoring element that exerts a force on the working plunger, at least part of the time, in the direction of the rear side, a gas inlet opening for supplying a compressed gas into the internal space and a gas outlet opening for discharging the gas from the internal space, the compressed gas motor comprising:
a control plunger arranged in the internal space between the working plunger and the closed rear side such as to be mobile in linear direction, whereby the control plunger, in a first position, covers the gas outlet opening and does not cover the gas inlet opening and, in a second position, covers the gas inlet opening and does not cover the gas outlet opening, the control plunger is supported to be mobile with respect to the working plunger, and a catch element that is arranged on the working plunger and/or control plunger and pulls the control plunger in the direction of the working plunger, at a first distance, when the working plunger moves away from the control plunger. |
