Structure of mechanism

Function The piston 3 is moved by a slide mechanism with slider and crank BCD. The eccentric 1, attached to the handle 6, revolves around a fixed axis B. The element 7 in E form a pivotal with the slide 8 which rotates about a fixed axis E. K of the finger the piston rod 2 slides into the slide 8. When 1 eccentric rotates, the pistons 2 and 3 receive an alternating movement. The length of the piston stroke 2 depends on the position of the lever 4 and its attachment to the toothed segment b.
