Definitions

  • the present invention concerns an air compressor unit for inflating vehicle tyres, including a 12 N DC motor driving a reciprocating compressor through a crankshaft and a connecting rod arrangement and a gear with a gear ratio with crankshaft rpm relative to drive shaft rpm in the range 3:10 to 1:10 inserted between the drive shaft of the motor and the crankshaft.
  • Such a compressor unit is disclosed in GB A 2 157 775, providing a low-cost unit with only one piston and a gear with only one step.
  • crankcase, gear housing and flange for mounting the motor in the unit are cast in one piece, that the compressor cylinder has laterally projecting lugs with screw holes and is releasably fastened to the crankcase with screw connections, and that the cylinder is provided with a detachable valve arrangement at the end opposite the crankcase.
  • the flange for mounting the motor covers the end face around the drive shaft and has an annular collar enclosing the abutting end of the motor, and that the collar is provided with mounting holes for fastening a jacket protecting the motor.

Abstract

L'invention concerne un ensemble compresseur destiné aux installations fixes dans les automobiles ou pouvant être utilisé dans une unité séparée, permettant de gonfler et éventuellement de réparer les pneus crevés. Cet ensemble comprend un compresseur (16) à piston conventionnel doté d'un vilebrequin (10) entraîné par un moteur (6) 12V CC. Le carter (4) de moteur, le carter (3) d'engrenage et le flasque (2) permettant le montage du moteur (6) sont coulés d'une seule pièce. Le cylindre de compresseur comprend des pattes qui s'avancent latéralement et qui comportent des trous de vis. Il est monté de manière amovible sur le carter du moteur au moyen d'éléments de raccord vissés. Le cylindre (16) est équipé d'un ensemble (19) soupape amovible placé à l'extrémité opposée au carter du moteur. Ce système permet de remplacer le cylindre (16) de manière à permettre l'utilisation de l'ensemble dans différentes applications, étant donné qu'il est possible de modifier sélectivement la course, le diamètre de cylindre et le volume mort dans le haut du cylindre de compresseur afin d'adapter la cylindrée, la pression de refoulement et le débit volume.
