Abstract

The compressor has a protective casing (1), a ventilator (2) to directly cool compression heads (3), and a radiator at an air outlet of the casing. The ventilator is placed upstream, so as to directly cool cylinders and cylinder heads of the compressor. A self-supporting structure includes two walls for supporting the compressor.

Description

DESCRIPTION L'invention concerne un compresseur à pistons sec, compresseur n'utilisant pas d'huile, à destination du secteur ferroviaire, qui est entièrement capoté afin d'améliorer l'insonorisation et de le protéger des agents externes. Ledit compresseur non lubrifié est fermé par un caisson (1) de surpression et d'insonorisation. Il est doté d'un ventilateur (2) en extrémité (entrée d'air) qui a l'avantage d'envoyer de l'air froid non réchauffé par un radiateur, sur les cylindres (5) et culasses (6). La structure du compresseur est une structure moto-compresseur (7) autoportante. En effet il y a sur ce compresseur une absence de châssis permettant d'améliorer le poids et l'encombrement à puissance égale. Cette structure autoportante est composée du groupe moto-compresseur (7) et de deux parois (8) situées aux extrémités du groupe. Cet ensemble complet permet d'éviter de devoir mettre en sus un châssis. Le radiateur (4) du compresseur est placé en sortie d'évacuation d'air du caisson ce qui a pour conséquence de souffler de l'air réchauffé sur le radiateur (4) et ainsi permet d'éviter la formation de glace par des températures très négatives due à la présence de condensats dans le radiateur. Les cylindres (5) du compresseur à pistons sec sont disposés en « Y » ce qui permet ainsi de refroidir les cylindres (haute pression et basse pression) de façon identique. Le compresseur au vu de cette invention a l'avantage d'avoir un encombrement (dimensions, poids) optimal à puissance égale.The invention relates to a dry piston compressor, compressor not using oil, for the rail sector, which is completely covered to improve the soundproofing and protect external agents. Said non-lubricated compressor is closed by a box (1) of pressure and soundproofing. It has a fan (2) at the end (air inlet) which has the advantage of sending cold air unheated by a radiator, on the cylinders (5) and cylinder heads (6). The structure of the compressor is a self-supporting motor-compressor structure (7). Indeed there is on this compressor a lack of chassis to improve the weight and size at equal power. This self-supporting structure is composed of the motor-compressor unit (7) and two walls (8) located at the ends of the group. This complete set avoids having to add a chassis. The radiator (4) of the compressor is placed at the outlet of the air outlet of the casing, which has the effect of blowing heated air on the radiator (4) and thus makes it possible to prevent the formation of ice by temperatures very negative due to the presence of condensate in the radiator. The cylinders (5) of the dry piston compressor are arranged in "Y" which thus allows the cylinders (high pressure and low pressure) to be cooled in an identical manner. The compressor in view of this invention has the advantage of having an overall size (dimensions, weight) optimal to equal power.
