Abstract

La pompa comprende un cinematismo per il movimento degli stantuffi (10) del tipo avente un piano (12) solidale all'albero (11) di entrata del moto e inclinato rispetto al piano perpendicolare all'asse dell'albero (11) stesso, detto piano inclinato (12) agendo con vincoli di appoggio unilaterale sulla estremità posteriore degli stantuffi (10) per attuare la corsa di mandata di questi; è prevista una piastra (20) vincolata all'estremità posteriore di ciascun stantuffo (10) con un vincolo di appoggio che fornisce allo stantuffo (10) una reazione con componente parallela all'asse dello stantuffo stesso ed avente lo stesso verso della corsa di ritorno dello stantuffo (10); la porzione centrale della piastra (20) appoggia sopra un elemento-fulcro (30) coassiale con l'albero (11), atto a fornire alla piastra (20) una reazione con componente parallela agli assi degli stantuffi e avente lo stesso verso della corsa di ritorno degli stantuffi (10).The pump includes a kinematic mechanism for the movement of the pistons (10) of the type having a plane (12) integral with the input shaft (11) and inclined with respect to the plane perpendicular to the axis of the shaft (11) itself, called inclined plane (12) acting with unilateral restraint constraints on the rear end of the pistons (10) to carry out the delivery stroke of these; a plate (20) is provided constrained to the rear end of each piston (10) with a support constraint which provides the piston (10) with a reaction with component parallel to the axis of the piston itself and having the same direction as the return stroke of the plunger (10); the central portion of the plate (20) rests on a fulcrum element (30) coaxial with the shaft (11), adapted to provide the plate (20) with a reaction with component parallel to the axes of the pistons and having the same direction of travel return of the pistons (10).
