[Prior art] There are many types of conventional air compressors, such as rotary, screw, and reciprocating air compressors. The operating principles are different, but the purpose is to use mechanical energy to compress the gas to high pressure to make the gas burst out instantly. .疋 ίο 15 As shown in Figure i, in the case of a general reciprocating air compressor, a periodic reciprocating motion is used to supercharge and eject the airflow. Wang should include an internally defined upright cylindrical compression space 11〇 A steam cylinder A, a circular piston 12 with an area corresponding to the cross section of the cylinder and abutting on the inner wall of the steam cylinder u, and a shaft 13 extending axially and fixed at the center of the piston 12. The pressure cylinder 11 includes a bottom wall m having an inlet port 112 and an exhaust port 113 for one-way gas inflow and outflow, respectively. The shaft 13 is driven by a preset power to drive the piston 12 in a non-compressed position away from the bottom wall 111 and allow air to pass from the air inlet 112 to the eighth room 110 and a flat pressure on the bottom wall U1. ^ L 、, The compaction position rolled and rolled from the exhaust port 113 is reciprocated up and down. This type of compressor has been running 葙 φ to the direction of ““ _private. The 12-peripheral edge of the piston is in friction with the inner wall of the pneumatic cylinder Π, which results in a loss of Awen and affects mechanical performance. In addition, the know-how uses a single axis to move the up and down movement directions of the ^^ 13 work system, which is prone to unstable and slight lateral deviations of 1 ^ door deviation, resulting in greater wear and tear.

The compression mechanism 3 includes a shaft 31 that is pivotally arranged at the fan-shaped axis center. -A rectangular plate-shaped piston 32 extending from the shaft 31 toward the arc-shaped wall 22 to form a free end 321 and not contacting the inner wall surface of the cylinder 2 and most of the distribution are embedded in the left and front and rear edges of the piston 32 Component 33. In this embodiment, an example of a bead assembly 33 in which f-parallel intervals are distributed at each side edge is illustrated. Each bead assembly 33 includes an elongated bead M extending along the length of the corresponding side edge, and a A pad 332 is placed between the bead 33i and the piston 32. The pressing strips 331 are made of abrasion-resistant, heat-insulating and financially-heating composite materials, and each shrapnel M is 10, which will push the corresponding 331 elastically outward, so that the pressing bar 33i slightly protrudes: lightly The inner wall surface of the steam pressure red 2 makes the piston 3 airtight. Referring to FIG. 2, FIG. 3 and FIG. 5 at the same time, FIG. 5 is a plan development view of some elements of this embodiment. The driving mechanism 4 includes two fixed walls M, which are fixed at the opening 205 above the cylinder 2 upright and opposite to each other and spaced apart from each other. The 41 crankshafts 42 and the connecting rods 43 between the center of the crankshaft c and the free end 3U of the piston 32 are respectively pivotally mounted on both ends thereof. At the same time, referring to FIG. 6 and FIG. 7, the running trajectory of the upper end of the connecting rod 43 is wound in a circular shape by the rotation of the crankshaft 42. The inner wall surface of the shaped wall 22 drives the piston 32 centered on the shaft 31 to swing back and forth between a non-compressed position as shown in FIG. 6 and a compressed position as shown in FIG. 7. When the piston 32 is in the non-compressed position, its free end 321 is far from the base wall n and allows air to enter the compression space 20 through the air inlet 211. When the piston 32 is located at the pressure 1238223 [Description of the main symbols of the drawings] 2 Steam cylinder 31 Shaft 20 Compression space 32 Piston 201 Opening 321 Free end 21 Base wall 33 Bead assembly 211 Inlet 331 Bead 212 Exhaust port 332 Shrapnel 22 Curved wall 4 Driving mechanism 23 First side wall 41 Fixed wall 24 Second side wall 42 Crankshaft 25 Third side wall 43 Connecting rod 3 Compression mechanism 9
