Title (EN) LINEAR PISTON PUMP HAVING PARASITIC VOLUMES
(FR) POMPE À PISTON LINÉAIRE À VOLUMES PARASITAIRES
(DE) LINEARKOLBENPUMPE MIT PARASITÄREN VOLUMINA
Abstract:
(EN) The invention relates to a linear piston pump comprising: a closed pump cylinder (1), in the working space (2) of which at least one pump piston (3.1, 3.2) runs in an oscillatingly driven manner, a pump chamber (4) thus being formed, a pump inlet (5) having an inlet valve (7), a pump outlet (9) having an outlet valve (8), at least one parasitic volume (14.1, 14.2) on the piston outside (13.1, 13.2) of the pump piston (3.1, 3.2), and a ventilation fluid connection (V) between the parasitic volume (14.1, 14.2) and the pump outlet (9) downstream of the outlet valve (8) of the pump outlet.
(FR) L'invention concerne une pompe à piston linéaire comprenant : - un cylindre de pompage (1) fermé, dans la chambre de travail (2) duquel au moins un piston (3.1, 3.2) de pompe circule en étant entraîné de manière oscillante de manière à former une chambre (4) de pompe, - une entrée (5) de pompe pourvue d'une soupape d'admission (7), - une sortie (9) de pompe pourvue d'une soupape d'échappement (8), - au moins un volume parasitaire (14.1, 14.2) sur le côté extérieur (13.1, 13.2) du piston (3.1, 3.2) de pompe, et - une liaison fluidique de ventilation (V) entre le volume parasitaire (14.1, 14.2) et la sortie (9) de pompe fluidiquement derrière la soupape de sortie (8) de ladite sortie.
(DE) Eine Linearkolbenpumpe umfasst: - einen geschlossenen Pumpzylinder (1), in dessen Arbeitsraum (2) mindestens ein Pumpkolben (3.1, 3.2) unter Bildung einer Pumpkammer (4) oszillierend angetrieben läuft, - einen Pumpeneinlass (5) mit einem Einlassventil (7), - einen Pumpenauslass (9) mit einem Auslassventil (8), - mindestens ein parasitäres Volumen(14.1, 14.2) auf der Kolbenaußenseite (13.1, 13.2) des Pumpkolbens (3.1, 3.2), und - eine Ventilations-Fluidverbindung (V) zwischen dem parasitären Volumen (14.1, 14.2) und dem Pumpenauslass (9) strömungstechnisch hinter dessen Auslassventil (8).
