摘要： A vacuum pump comprises: a rotor; a stator; a first heating section configured to heat the stator cylindrical portion to a temperature for reducing product accumulation; an exhaust pipe provided at a housing storing the rotor and the stator to discharge gas discharged by the rotor and the stator to an outside of the housing; a second heating section configured to heat the exhaust pipe to a temperature for reducing product accumulation; and a gas passage container arranged in the housing, having an inlet port into which gas discharged through a gap between the rotor cylindrical portion and the stator cylindrical portion flows and an outlet port from which inflow gas flows to the exhaust pipe, and heated to a temperature for reducing product accumulation. A gas-inflow-side end portion of the exhaust pipe is inserted into the outlet port of the gas passage container through a clearance.

摘要： A slide valve comprises: a casing having a pair of facing flow channels; a slide plate inserted into and removed from a space between the flow channels; and an annular sealing body slidingly moving in a facing direction of the flow channels inside the casing and coming into contact with the slide plate inserted between the flow channels to bring the slide valve into a closed state. A first sealing member sealing a gap between the sealing body and the inner peripheral wall surface is disposed on an inner peripheral surface of the annular sealing body and a second sealing member sealing a gap between the sealing body and the outer peripheral wall surface is formed on an outer peripheral surface of the annular sealing body.
