Ejector device

Abstract

Abstract PURPOSE:To simplify construction by forming multi-stage nozzle parts which are combinedly used as diffusers between one block body on which these are provided and the other block body, in plural block bodies in an ejector device. CONSTITUTION:In an ejector device 20 consisting of block bodies 22, 24, an air introducing port 26 is formed on one end part of the block body 24, vacuum ports 28, 30, 32 ar formed in parallel on its center part, and an exhaust port 34 is formed on its other end part. A chamber 38 is constructed so as to gradually expand in its section, along a linear slope extending from a nozzle part 36a, thereby enabling a multi-stage nozzle parts 36b-36d to be combinedly used as diffusers in order. Thereby, an airtight device body which is easy to assemble can be manufactured at a low cost.
