Abstract:
A compressor comprising:a drive shaft; a drive plate, which is supported by the drive shaft; a plurality of pistons, which are arranged about the axis of the drive shaft and are coupled to the drive plate, wherein each piston includes two opposed piston heads, and the drive plate converts rotation of the drive shaft into reciprocation of each piston; a plurality of pairs of compression chambers, wherein each pair of compression chambers correspond to the piston heads of one of the pistons; a pair of discharge chambers, wherein each discharge chamber corresponds to one of each pair of compression chambers, wherein each compression chamber is connected to a corresponding one of the discharge chambers through a respective discharge port, wherein the piston heads of each piston compress gas in the corresponding compression chambers and discharge compressed gas from the corresponding compression chambers to the corresponding discharge chambers, wherein each discharge chamber has an outlet for compressed gas; and a limit wall formed in each discharge chamber, wherein each limit wall limits the flow of compressed gas in the corresponding discharge chamber so that compressed gas in the corresponding discharge chamber flows circularly about the axis of the drive shaft in one direction from all the corresponding discharge ports toward the outlet.
