Abstract

Il presente trovato si riferisce ad una pompa ad ingranaggi regolabile con almeno due coppie di ingranaggi, che sono disposte l'una accanto all'altra, in un corpo. Alle coppie di ingranaggi disposte ad asse parallelo è associato un canale di aspirazione preferenziale comune e i canali in pressione associati sono connessi direttamente o indirettamente. Una delle coppie di ingranaggi presenta un ingranaggio azionante, che è accoppiato in modo non rotante con un albero di azionamento, mentre l'altra o le ulteriori coppie di ingranaggi presentano un ingranaggio alternativamente azionato o disaccoppiabile dall'albero di azionamento. Ciascun ingranaggio, alternativamente azionato o disaccoppiabile, è fissabile nello stato disaccoppiato. L'ingranaggio alternativamente azionato o disaccoppiabile dall'albero di azionamento è accoppiabile mediante accoppiamento ad attrito all'albero di azionamento, rispettivamente è fissabile contro il corpo per mezzo di accoppiamento ad attrito o di accoppiamento di forma di per sé noto.The present invention relates to an adjustable gear pump with at least two pairs of gears, which are arranged next to each other, in a body. A common preferential suction channel is associated with the pairs of gears arranged on a parallel axis and the associated pressure channels are connected directly or indirectly. One of the gear pairs has a driving gear, which is coupled in a non-rotating manner with a drive shaft, while the other or the further gear pairs have a gear alternately driven or decoupled from the drive shaft. Each gear, alternatively driven or decoupled, can be fixed in the decoupled state. The gear alternatively driven or decoupled from the drive shaft can be coupled by frictional coupling to the drive shaft, respectively can be fixed against the body by means of frictional coupling or coupling of known shape.
