A valve mounting arrangement for a refrigeration compressor which presents a compression chamber (3) closed by a valve plate (4, 20) having a suction orifice (5, 21) closed by a valve element (10) having a mounting end portion (11). The mounting arrangement comprises: a first retaining means (8, 9) to retain the mounting end portion (11) of the valve element (10) inside a receiving recess (23) of the valve plate (4, 20); and at least one orientation projection (40) carried by receiving recess (23) and/or the mounting end portion (11) of the valve element (10) and to be fitted into an orientation recess (30) in the other part; and/or a second retaining means (50) provided between the receiving recess (23) and the mounting end portion (11) of the valve element (10), so as to avoid the latter from moving from the receiving recess (23) before mounting the first retaining means.

L'invention concerne un dispositif de montage de soupape pour un compresseur de réfrigération présentant une chambre de compression (3) obturée par une plaque de soupape (4, 20) comportant un orifice d'aspiration (5, 21) obturé par un élément de soupape (10) comportant une partie d'extrémité de montage (11). Le dispositif de montage comprend : un premier moyen de retenue (8, 9) servant à retenir la partie d'extrémité de montage (11) de l'élément de soupape (10) à l'intérieur d'un renfoncement récepteur (23) de la plaque de soupape (4, 20) ; et au moins une protubérance d'orientation (40) portée par le renfoncement récepteur (23) et/ou la partie d'extrémité de montage (11) de l'élément de soupape (10) et destinée à s'emboîter dans un renfoncement d'orientation ; et/ou un deuxième moyen de retenue (50) formé entre le renfoncement récepteur (23) et la partie d'extrémité de montage (11) de l'élément de soupape (10), de manière à empêcher celle-ci de sortir du renfoncement récepteur (23) avant le montage du premier moyen de retenue.
