摘要： A boring and/or percussion hammer comprises an electrodynamic linear drive and a pneumatically damped percussion mechanism which is provided with a drive piston driven by the linear drive during the reciprocating movement thereof, an impact piston and a pneumatic spring arranged between the drive and impact pistons. An air-supply device comprises a pumping element, which is linearly forth and back movable for generating airflow. The pumping element is connected to the drive piston in such a way that the movement thereof is transmitted to said pumping element, thereby the cooling air is transported by an air channel for cooling heat generated elements.

摘要： The invention relates to a pneumatic spring percussion mechanism comprising a driving piston moving back and forth in a housing of the percussion mechanism and a percussion piston, wherein a pneumatic spring is configured between the driving piston and the percussion piston. The movement of the driving piston can be transmitted to a percussion piston by means of said pneumatic spring. The driving piston can be driven by an electric linear motor and is connected to an aromatic of the linear motor, forming a single piece therewith. This arrangement makes it possible to eliminate the use of a conventional rotary motor and a crank mechanism to drive the driving piston.

摘要： The high flow water return fitting of the present invention is designed to connect directly to the end of a water return pipe in a swimming pool, spa, or the like. Water return fittings have been available for many years and have the primary purpose of returning filtered water back into a swimming pool, spa, or the like. However, the water return fitting of the present invention does not only return water into the swimming pool, it also substantially increases the water outflow so that a greater area of water in the pool can be circulated or agitated. The present invention has a uniquely curved nozzle with a flat flange. Both the curvature of the nozzle and the flat flange promote the accumulation of water within the nozzle so as to build up pressure that then pushes the water out a small outlet hole at a greater rate than does a conventional water return fitting. The outflow from the nozzle then creates a low pressure condition within a mixing chamber. Thus, the low pressure condition draws water in from the swimming pool through various louvers into the mixing chamber where it is mixed with the outflow of water from the nozzle to increase the total amount of water flowing out of the water return fitting of the present invention.
摘要翻译：本发明的高流量回水配件被设计成直接连接到游泳池，温泉等中的回水管的端部。回水管件已有多年可用，其主要目的是将过滤后的水返回游泳池，水疗中心等。然而，本发明的回水配件不仅将水返回到游泳池中，还大大增加了水流出，使得池中的更大面积的水可以循环或搅动。本发明具有具有平坦凸缘的独特弯曲的喷嘴。喷嘴和平坦凸缘的曲率均能促进喷嘴内的水积聚，以便增加压力，然后将压力以比传统的回水配件更大的速率推出小出口孔。然后，喷嘴的流出在混合室内产生低压状态。因此，低压条件将游泳池内的水通过各种百叶窗吸入混合室，混合室与喷嘴的水流出混合，从而增加从本发明的回水配件中流出的水的总量。
