Abstract

In the compression mechanical unit (3) of the multi-cylinder notary compressor (M), the first cylinder (6A) and the second cylinder (6B) are arranged with an insert plate (2) that is inserted between them, room The cylinders (Sa, Sb) imported low pressure gas to the inner diameter of the cylinder. Each (6A, 6B) is formed, and the posterior chamber (11a, 11b) will contact the cylinder chamber. (Sa, Sb) through the barrier groove (10a, 10b) will be provided. Back pressure inlet (20) is Opened into the posterior chamber (11b) from the end surface of the cylinder (6B), high pressure is introduced. To provide a high back pressure to the end part behind the barrier and compression is performed. Let the cylinder chamber (Sb), or low pressure is brought in and the compression is stopped in the chamber. Cylinder (Sb) to cause the cylinder chamber (Sb) to enter state, causing the cylinder to rest. The external opening angle (ha) located away from the inlet rotating shaft, back pressure (20) shall be located on the perimeter side of the distal surface (bb) of the distal part behind the block. In the condition of causing the cylinder to rest
