(FR) COMPRESSEUR À PISTON À LABYRINTHE
Abstract
(DE)
Der Labyrinthkolbenkompressor (1) umfasst einen Zylinder (10), einen im Zylinder (10) angeordneten Kolben (20), sowie eine Kolbenstange (24), wobei sich die Kolbenstange (24) in einer Längsrichtung (L) erstreckt und mit dem Kolben (20) verbundene ist, und wobei der Kolben (20) innerhalb des Zylinders (10) in Längsrichtung (L) hin und her beweglich ist, wobei der Zylinder (10) einen ersten Zylinderdeckel (11) umfasst, wobei im ersten Zylinderdeckel (11) ein Einlassventil (90) sowie ein Auslassventil (91) angeordnet sind, und wobei das Einlassventil (90) und das Auslassventil (91) symmetrisch bezüglich einer in Längsrichtung (L) entlang der Kolbenstange (24) verlaufenden Symmetrieebene (S) angeordnet sind.
(EN)
The labyrinth piston compressor (1) comprises a cylinder (10), a piston (20) located in the cylinder (10), and a piston rod (24), the piston rod (24) extending in a longitudinal direction (L) and being connected to the piston (20), the piston (20) being movable back and forth inside the cylinder (10) in the longitudinal direction (L), the cylinder (10) having a first cylinder cover (11), an inlet valve (90) and an outlet valve (91) being located in the first cylinder cover (11), and the inlet valve (90) and the outlet valve (91) being symmetrical with respect to a plane of symmetry (S) running along the piston rod (24) in the longitudinal direction (L).
(FR)
L’invention concerne un compresseur à piston à labyrinthe (1) comprenant un cylindre (10), un piston (20) monté dans le cylindre (10) ainsi qu’une tige de piston (24), la tige de piston (24) s’étendant dans une direction longitudinale (L) et étant reliée au piston (20), et le piston (20) effectuant un mouvement de va-et-vient dans la direction longitudinale (L) à l’intérieur du cylindre (10), ledit cylindre (10) comprenant un premier couvercle de cylindre (11), une soupape d’admission (90) et une soupape d’échappement (91) étant montées dans le premier couvercle de cylindre (11), et la soupape d’admission (90) et la soupape d’échappement (91) étant montées de manière symétrique par rapport à un plan de symétrie s’étendant dans la direction longitudinale (L) le long de la tige de piston (24).
