Positive displacement air compressor with folded blade type swing mechanism

Abstract

The invention discloses a positive displacement air compressor with a folded blade type swing mechanism. The swing mechanism comprises a columnar rotor, folded blades and supporting sliding blocks. Folded blade placing grooves are axially formed in the outer side wall of the columnar rotor. The folded blades are arc-shaped blades, and the radian of the inner side faces of the folded blades is matched with the radian of the folded blade placing grooves. The supporting sliding blocks are arranged at the two ends of each folded blade placing groove correspondingly. The two side edges of each folded blade are hinged to the columnar rotor and the supporting sliding blocks correspondingly. The supporting sliding blocks are embedded into rotary sliding rings which are coaxial with a working cavity through embedding grooves. End caps are arranged at the two ends of the working cavity. An eccentric bearing is arranged in the center of each end cap. Supporting shafts are arranged at the two ends of the columnar rotor. The swing mechanism is inserted into the working cavity to make the supporting shafts penetrate through the rotary sliding rings to be fixed to the eccentric bearings in the centers of the end caps in an inserted mode. According to the positive displacement air compressor, through the structural design of the swing mechanism, the columnar rotor and the supporting sliding blocks are in a non-concentric rotation state during rotation, and the purposes of inlet-air compression and exhausting are achieved by forming a changeable volume cavity in a stator shell.

Description

technical field [0001] The invention relates to a volumetric air compressor, in particular to a volumetric air compressor with a flap-type rotary mechanism. Background technique [0002] In the field of air compressors, it mainly includes piston air compressors, sliding vane air compressors, screw air compressors, and centrifugal air compressors.
