Zusammenfassung: | A hard seal, positive displacement pump is provided which may be included within a fluid delivery system. The pump includes a housing, a sleeve disposed radially within the housing, and a piston disposed radially within the sleeve. An outer shape of a first end of the sleeve contacts a correspondingly-shaped inner shape of a first end of the housing, thereby sealing the first end of the sleeve within the first end of the housing. The piston is radially and axially moveable within the sleeve, and an axially-reciprocating motion of the piston within the sleeve opens and closes a pump chamber defined between a first end of the piston and a first end of the sleeve.
Se proporciona una bomba de desplazamiento positivo con junta dura que se puede incluir dentro de un sistema de administración de líquido. La bomba incluye una carcasa, un manguito dispuesto radialmente dentro de la carcasa y un pistón dispuesto radialmente dentro del manguito. Una forma externa de un primer extremo del manguito se pone en contacto con una forma interna correspondientemente formada de un primer extremo de la carcasa, sellando así el primer extremo del manguito dentro del primer extremo de la carcasa. El pistón es radialmente y axialmente móvil dentro del manguito, y un movimiento axialmente alternativo del pistón dentro del manguito abre y cierra una cámara de bomba definida entre un primer extremo del pistón y un primer extremo del manguito. |
