Abstract

UNA BOMBA VOLUMETRICA POSITIVA COMPRENDE UNA CAMARA DE BOMBA DE VOLUMEN VARIABLE (16-1) Y UN MECANISMO DE ACCIONAMIENTO (26-1) QUE TIENE UN ELEMENTO DE DESPLAZAMIENTO (25-1) PARA REDUCIR EL VOLUMEN DE LA CAMARA DE BOMBA (161). EL LIQUIDO ENTRA A LA CAMARA DE BOMBA (16-1) DESDE UNA CAMARA DE SUMINISTRO (15-1) SITUADA CONTIGUA A RODEANDO EL LIMITE EXTERIOR LATERAL DE LA CAMARA DE BOMBA (15-1) MEDIANTE UNA PASO DE ENTRADA CONTROLADO POR LA VALVULA (17-1) QUE SE ABRE A LA CAMARA DE BOMBA (16-1) EN UN ORIFICIO DE ENTRADA ALARGADO DE TIPO BRECHA. EL PASO DE ENTRADA PERMITE QUE EL LIQUIDO CIRCULE DESDE LA CAMARA DE SUMINSTRO (15-1) A LA CAMARA DE BOMBA (16-1) SIN PERDIDA SUSTANCIAL DE LA PRESION.A POSITIVE VOLUME PUMP INCLUDES A VARIABLE VOLUME PUMP CHAMBER (16-1) AND A DRIVE MECHANISM (26-1) THAT HAS A DISPLACEMENT ELEMENT (25-1) TO REDUCE THE VOLUME OF THE PUMP CHAMBER (161) . THE LIQUID ENTERS THE PUMP CHAMBER (16-1) FROM A SUPPLY CHAMBER (15-1) LOCATED WITH IT SURROUNDING THE EXTERNAL SIDE LIMIT OF THE PUMP CHAMBER (15-1) THROUGH AN INPUT PASS CONTROLLED BY THE VALVE (17-1) THAT OPENS TO THE PUMP CHAMBER (16-1) IN A LONG ENTRANCE HOLE OF THE GAP TYPE. THE ENTRY STEP ALLOWS THE LIQUID TO CIRCULATE FROM THE SUPPLY CHAMBER (15-1) TO THE PUMP CHAMBER (16-1) WITHOUT SUBSTANTIAL LOSS OF PRESSURE.
