MULTICYLINDER COMPRESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a multicylinder compressing device capable of increasing a gas inflow into a housing without enlarging a suction opening of a bearing plate. SOLUTION: A plurality of suction openings 12a are circumferentially provided with certain intervals in between on the bearing plate 12 journaling a crankshaft 9. An inverted dish shaped cover material 14 is attached to an upper part of the bearing plate 12 and it covers the plurality of suction openings 12a. A sealed space S is formed in a space with the bearing plate 12 and an inlet 14a larger than the suction openings 12a is formed in an upper part center of the cover material 14. A gas supply pipe 15 is attached to the inlet 14a, and it is connected with a gas supply source.
