ABSTRACT:
A method of assembling a reciprocating compressor, in which a piston for partitioning a cylinder into a compression chamber and a suction chamber is telescoped in the cylinder, a closure end plate is secured at an open end of the cylinder, the end surface of the piston and the bottom surface of the end plate define opposing sides of the compression chamber, the piston is perforated by a suction port for communicating between the compression chamber and the suction chamber, and a suction valve sits on the piston for opening and closing the suction port, comprising the following steps; (1) manufacturing in advance a plurality of closure end plate, the i-th end plate having a bottom surface formed by a projection of different height h.sub.i ; (2) defining two reference positions of the piston and cylinder, respectively, for the i-th compressor and measuring the interval D.sub.i between the reference positions; (3) selecting an end plate which has a projection of such a height that D.sub.i -h.sub.i equals a predetermined constant; and (4) securing the selected end plate to the cylinder of the measured compressor. The suction valve is seated on the recessed valve seat surface formed on the end surface of the piston. The outer surface of the suction valve (i.e., the surface confronting the compression chamber) is disposed in the same plane as or slightly below the top surface of the piston (i.e., non-recessed part of the piston's end surface).
