Summary: | A reciprocating pump assembly has a pump housing with a crankshaft. A plunger is connected to the crankshaft for pumping a fluid through a cylinder. The cylinder has a fluid inlet port and an opening that provides access to the cylinder. A suction cover is mounted in the opening and has a hub that is coaxial with an axis of the suction cover. A suction valve stop is mounted adjacent one of the fluid ports and has a spring retainer. A column extends from the spring retainer, and a bushing is mounted to the spring retainer for engaging and being retained by the hub of the suction cover. The suction cover guides the suction valve stop in operation and, when the suction cover is removed from the opening, the suction valve stop is removable.
Une pompe volumétrique alternative comprend un carter avec vilebrequin. Un piston plongeur est raccordé au vilebrequin pour pomper un liquide à travers un cylindre. Ce cylindre comprend un orifice d'aspiration de liquide et un orifice qui débouche sur le cylindre. Un fond d'aspiration occupe l'orifice et comprend un évasement coaxial avec un axe du fond d'aspiration. Une butée de clapet d'aspiration est contiguë à l'un des orifices d'aspiration de liquide et elle est munie d'une attache de ressort. Une colonne part de l'attache du ressort, et une douille est montée sur l'attache du ressort pour s'engager dans l'évasement du fond d'aspiration, et y être retenue. Ce fond d'aspiration guide la butée du clapet d'aspiration en fonctionnement et, lorsque le fond d'aspiration est dégagé de l'orifice, la butée du clapet d'aspiration peut s'escamoter. |
