Abstract
A multistage compressor for compressing a refrigerant for an automobile air conditioning system includes a body which has a front housing and a rear housing connected to each other with a cylinder block clamped therebetween. The cylinder block includes a plurality of sets of cylinder bores arranged parallel to, and around the longitudinal axis. Pistons are received within the cylinder bores to define a plurality of sets of compression chambers together with the walls of the cylinder bores. The sets of the compression chambers are fluidly connected to each other to provide a series of stages for compressing the refrigerant gas. The cylinder bores are arranged at equal angles around the longitudinal axis in each set of the compression chambers whereby the unbalanced force on the swash plate and the drive shaft is removed.
