摘要： A riding type sweeper with a rear-mounted engine and a driven sweeper roller located between the front axle and the rear axle, wherein the sweeper roller transports the dirt into a coarse dirt container disposed behind the sweeper roller, from which the fine dirt is suctioned off by a filter blower unit. The filter blower unit is arranged in the region before the rear-mounted engine in a vertically superpositioned arrangement, with the blower turbine together with the fine filter being arranged in a common box.

摘要： A compressed gas- or air-operated firearm, comprises a gun stock with a gun sleeve affixed to the gun stock and with a gun barrel having an associated compression cylinder adjacent the inner end thereof with a spring-actuated piston movable therein and an associated trigger mechanism which is movably supported within the gun sleeve by roller bearing structure. A power accumulator is arranged between the relatively movable parts and it biases the parts into a neutral position and includes structure for absorbing the reaction force due to the movement of the piston during operation of the weapon.
