Title: Multi-layer type vacuum pump and assembling method therefor
Inventor: CHIN JUNKAN
IPC: F04C25/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To control an axial space of a rotor by providing an elastic body on a partition constituting a continuous compression space by a set with a cover. SOLUTION: A compression space of each layer is formed by a cover 12 and a partition 13. An axis distance is a D distance previously set and an aperture 122 is an outlet for conveying, compressing and discharging each layer gas. The partition 13 is a symmetrical plate and is formed by engaging the symmetrical plate on a rotation axis to separate the compression space of each layer. Then, an annular groove is provided on the partition 13 at an appropriate position and an elastic body 17 is provided thereon. An accuracy control of a recess vessel distance J of a cover 12 is carried out by making the distance J slightly bigger than a thickness B of the partition 13. At the time of assembling, the elastic body 17 is urged by a compression of the partition 13 and the cover 12 and the partition 13 urges a cover end surface 123 of the cover 12 by an elastic force of the elastic body 17.  Thereby, the cover end surface 123 and a flat surface are arranged to accomplish a sealing and a compression space of each layer can be formed.
