Abstract
La pompa è munita di una serie di cilindri (11) disposti a stella, in ciascuno dei quali è scorrevole un pistone (32). Ciascun cilindro (11) è chiuso da una corrispondente testa (51) e comprende una valvola di aspirazione (40) ed una valvola di mandata (41) aventi una sede (46, 47) disposta in una piastra (50). La valvola dì aspirazione (40) è disposta all'estremità di un canale di aspirazione (57), il quale presenta una prima porzione (60) passante, che attraversa la piastra (50), una seconda porzione (62) formata tra la testa (51) e la piastra (50) e perpendicolare all'asse (12) del cilindro (11), ed una terza porzione (64) parallela all'asse (12). La valvola di mandata (41) ha una sede (47) tronco-conica in comunicazione con la camera di pompaggio (35) attraverso un condotto (39) pure passante attraverso la piastra (50). I due otturatori (42, 43) sono in ceramica e sono guidati da una corrispondente gabbia (44, 45).Figura 2.
