Abstract:
1. A piston assembling apparatus in a swash plate type compressor, which has a rotor and a swash plate on a driving shaft, for assembling a plurality of pistons coupled to the swash plate into a number of cylinder bores of a cylinder block having a center bore together with the cylinder bores, the apparatus comprising: cylinder block-fixing means for fixing the cylinder block in a space; vacuum absorbing means disposed in a position spaced apart by a predetermined height from a top surface of the cylinder block and for vacuum absorbing outer faces of the pistons so that the pistons are in positions where the pistons can be inserted into the cylinder bores; absorbing angle-maintaining means having an absorbing angle-maintaining face in its upper end corresponding to lower faces of the pistons in order to maintain an absorbing angle of each of the pistons absorbed by the vacuum absorbing means, the absorbing angle-maintaining means capable of entering the cylinder bores from under the cylinder block and leaving out of the same; assembly-descending means for pressing an upper end of the driving shaft to descend the assembly including the driving shaft, the rotor, the swash plate and the pistons toward the cylinder blocks so that the pistons are introduced into the cylinder bores; and elevating/descending means for elevating the absorbing angle-maintaining means toward the inside of the cylinder bores so that the absorbing angle-maintaining face comes into contact with a lower end of each of the pistons and for descending the absorbing angle-maintaining means at a rate substantially equal to a descending rate of the assembly-descending means upon actuation of the assembly-descending means.
