Member for regulating the flowthrough quantity of a pressure medium

The member is to make it possible to reduce automatically the speed of a compressed-air engine when the engine is not loaded (idle running). In the housing (5), a movable plate (4) is guided by diaphragms (3). In the working position illustrated, the air passes from the inlet (1) via bores in the plate (4) to the outlet (2). In the case of an increasing flowthrough quantity (reduction of engine load), the pressure difference rises above the plate (4) so that the latter snaps over into the idle-running position, in which the bores are closed by a sealing ring (6) except for an adjustable idle-running passage (7). On loading of the engine, the plate (4) snaps back into the working position. The speed of the unloaded engine is greatly reduced by the member, which increases safety in the driving of grinding discs. Moreover, air consumption and noise level in idle running are low. <IMAGE>

The present invention relates to a two-stroke rotary engine, wherein a plurality of cylinders and crankcases symmetrical to each other are installed around the output shaft, and the high speed torque generated in each crankshaft is a small gear integrated with the crankshaft and the engine outer case. It relates to a two-stroke rotary engine in which the engine body, that is, the cylinder and the crankcase, rotate in such a manner as to engage around a fixed fixed gear and transmit it to the output shaft with reduced rotational force. 본 발명은 출력축을 중심으로 모든 부분이 대칭 운동을 함으로서 회전 무게 중심이 항상 일정하여 진동이 적고, 종래의 왕복엔진에서 회전을 안정되게 하기 위해 부착하던 벨런싱 웨이트나 플라이휠과 같은 중량체가 없더라도 안정된 회전력을 얻을 수 있으며, 고속으로 분출되는 베기 가스의 힘을 회전력으로 첨가할 수 있고, 크랭크축에서 발생된 고속 회전력이 감속되어 출력 축에 전달됨으로 실용 회전수에 가까운 출력이 발생된다. 따라서, 경량이면서 고출력, 고효율, 저 진동의 엔진을 얻을 수 있게 된다. 본 발명은 자동차, 발전기, 선박 또는 기타 원동기용 엔진으로 사용될 수 있지만 출력축과 일체로 된 엔진 본체 즉, 중량체인 실린더와 크랭크케이스 및 크랭크축, 커넥팅로드, 피스톤이 회전됨으로서 원심력이 증가하는 자이로 효과로 헬리콥터의 엔진에 보다 효과적으로 적용될 수 있는 2행정 로우터리 엔진에 관한 것이다.

The latter is in the form of a tube surrounding the valve stem and normally held against a squared shoulder by an adjustable spring 25. The valve 19 is held on its seat by a spring 21 and carries projections 26 on its upper surface, which coact with the ball valve. and the valve stem under the valve 19 is fluted. The poppet valves are worked from a cam 7 on the crank-shaft 6 through tappet levers 8 pivoted on a plate adjustable angularly on the crank-shaft. In one position of the plate, the machine acts as a compressor. For the machine to act as a motor to start the main engine of a vehicle, the plate is moved to another position so that the poppet valves are moved sufficiently to unseat the ball valve and admit compressed air in succession to the cylinders. During this admission, the valves 22 close the passages to atmosphere and on the exhaust strokes both poppet valves may be held in such a position as to allow exhaust to pass by the fluted parts of the stem. The ports 28 act as terminal exhaust ports. Intermediate positions of the plate enable variations in the working to be effected. The valve 22 has adjustable packing 23.

一种径向液压柱塞马达

本发明涉及液压马达结构设计技术领域，具体的说，涉及一种径向液压柱塞马达，包括定子、定子内部的转子、位于定子与转子之间的柱塞、配流轴，所述柱塞的头部设有连接片，所述连接片的两侧设有两个球塞，所述两个球塞通过连杆和位于连杆两端的球塞销钉和连接在一起，所述连杆的中部设有用于与连接片连接的连杆销钉，所述定子的内壁的定子导轨各处平滑。本发明同普通的径向液压柱塞马达相比，与定子曲线导轨的接触多有了滚动摩擦的效果，由此分担了大部分由滑动摩擦要承担的摩擦力，承载力相同时，滚动摩擦比滑动摩擦带来的损耗要小的多，因此摩擦损耗更小，承载能力更强，噪声更低。同时该径向柱塞液压马达还提供了一种新型广义椭圆定子曲线导轨。

星形活塞式发动机

一种带有杯形活塞的星形活塞式发动机，活塞与偏心轴的周边接合，在各种情况下，活塞内均装有导向体，导向体径向向外浮动地安装在壳体上，在气缸盖内设有受压流体的出入口。为了利用简单且节省空间的结构实现工作活塞的自动控制，在气缸盖(9)或壳体的相应构件内，可调节地设置控制件(15)，此控制件连接在导向体(5)上，用以控制流体的出入口(19、20)。

一种高气压高效率活塞式气动马达

本发明涉及一种进气路程较短、无气路阻碍、效率更高的高气压高效率活塞式气动马达。这种高气压高效率活塞式气动马达包括有主体、输出轴与多个活塞连杆机构，活塞连杆机构可通过曲轴带动输出轴转动，其特征在于：主体上等分设有多个缸套孔，每个缸套孔内设有缸套，活塞连杆机构包括有活塞与连杆组件，活塞活动设在缸套内；主体具有内孔，主体的内孔安装有配气套，输出轴设在配气套内，配气套上沿轴向设有第一换气腔、第二换气腔以及多个配气孔。这种高气压高效率活塞式气动马达，通过对结构的改进，使其进气路程较短，气压能直接正面作用在活塞上，从而提高能量的转化效率，更适于高气压。
