A setting apparatus 30 in which a mandrel of a blind rivet is inserted into a hole 47 of a nose at the front end of the setting apparatus, and wherein a rivet body of the rivet is projected from the nose into a mounting hole of a workpiece. The mandrel is pulled rearward of the nose with a force capable of breaking the mandrel and expanding a shank of the rivet body so that the rivet is set in the workpiece by the expanded shank and a flange of the rivet body, followed by discharging of the broken mandrel from the setting apparatus. The force for pulling the mandrel is obtained from hydraulic pressure of a hydraulic cylinder 34. The hydraulic pressure is produced by a piston 41 which moves in a pneumatic cylinder 39 adjacent to the hydraulic cylinder. The nose 31 is axially aligned with an apparatus body 33 including the hydraulic cylinder and the pneumatic cylinder 39 along the longitudinal direction of the setting apparatus 30 from the front end to the rear end thereof. A discharge path for the broken mandrel is formed 5 by a hollow tube extending from the mandrel inserting hole 47 of the nose through (tubes 49 and 50 of) the apparatus body and (a tube 51 of) the hydraulic cylinder to the rear end 53 of the setting apparatus.

摘要:
There is disclosed a scroll compressor capable of improving the oil separating device of a refrigerant gas discharged from a scroll compression element to effectively suppress the amount of oil to be discharged through a discharge tube. The scroll compressor has, in a sealed container, a scroll compression element, a motor element which drives the scroll compression element, and a support frame having a bearing portion which keeps a shaft of the motor element, and provided with a communication path. The scroll compressor further includes a shield plate which extends from the support frame to the motor element side to surround the periphery of the bearing portion, and a guide member provided at an outlet of the communication path to guide the discharged gas in the direction of the shield plate.
