Disclosed herein is a wobble diaphragm pump having a housing with an open neck. A wobble piston can be passed through the open neck and fit onto the pump motor shaft. A separate support ring is fastened to the housing to close the open neck and provide a circumferential support surface for the diaphragm. The support ring also includes locking projections that mate with recessed features in the housing and a valve head to properly align and unite these components during assembly.
La présente invention concerne une pompe à membrane à plateau oscillant qui possède un boîtier pourvu d'une encolure ouverte. On peut faire passer un piston à plateau oscillant à travers cette encolure ouverte et l'adapter au vilebrequin du moteur de la pompe. Une bague de support séparée est fixée sur ce boîtier de façon à fermer l'encolure ouverte et fournir une surface de support périphérique à la membrane. Cette bague de support comprend aussi des projections de blocage assorties à des éléments en creux de ce boîtier et à une tête de clapet afin d'aligner et d'unifier correctement ces éléments pendant l'assemblage.
