OBL plunger stroke adjustment mechanism The adjustment of the plunger stroke is linear, accurate, and without backlash. Turning the adjustment knob causes the wedge "A" to slide vertically within the grooved pin "B" fitted, with zero clearance, in the eccentric "C". The result is that the vertical movement of the wedge is translated into horizontal movement of the eccentric and, in turn, the plunger. High adjustment accuracy is further enhanced by the use of the gravitational dial Principio di regolazione OBL della corsa del pistone La regolazione della corsa del pistone e lineare, precisa e priva...
