带固定直径壳体的活塞泵缸体1绕固定的轴A旋转,活塞3在缸体1内作往复运动,活塞杆b端部带有滚子a。壳体2的断面形状保证经过轴心A的直径尺寸处处相等,例如可以取为心形。当缸体转动时,滚子a沿壳体滚动,油泵的活塞3运动。带摇摆缸体的回转活塞泵曲柄1绕固定的轴A旋转,曲柄和三个对称布置的活塞2组成回转副,活塞在摆动缸体3内的摇杆d里滑动,当缸体摆动时,打开或关闭进入孔。液体经总管道a吸入,经总管道b压出。圆柱活塞活塞泵圆形转子1绕固定的轴A旋转,转子具有三个
A piston pump cylinder 1 with a fixed-diameter housing rotates about a fixed axis A, the piston 3 reciprocates within the cylinder 1, and the end of the piston rod b carries a roller a. The cross-sectional shape of the housing 2 ensures that the diameter dimension passing through the axis A is equal everywhere, for example, it can be in the form of a heart. When the cylinder rotates, the roller a rolls along the housing, and the piston 3 of the oil pump moves. The rotary piston pump with a swing cylinder crank 1 rotates around a fixed axis A, the crank and the three symmetrically arranged piston 2 constitute a swivel pair, the piston slides in the rocker d in the swing cylinder 3, and when the cylinder swings, Open or close the access hole. Liquid through the main pipe a inhalation, the total pipeline b pressure out. Cylindrical piston piston pump The circular rotor 1 rotates about a fixed axis A, with three rotors
