A rotary pump consisting of multiple stages of vane pumps connected together, which is a multi-stage type in which a high degree of vacuum can be obtained by sequentially compressing and discharging gas using the vane pumps in each stage. In vane pumps,
A multistage vane pump characterized by being equipped with a muffler that collects the gas discharged by each stage of the vane pump and reduces the exhaust noise of the gas. 2. The silencer includes a concentration chamber that collects the gas discharged by the vane pumps of each stage, a sound absorbing material provided in the concentration chamber that reduces exhaust noise by passing the gas collected in the concentration chamber, and 2. The labyrinth according to claim 1, wherein the labyrinth is connected to a chamber and has a winding shape and an inner diameter that changes in size, and the labyrinth is a labyrinth in which the gases that have passed through the sound absorbing material are caused to collide with each other and cause mutual interference. Multi-stage vane pump.
