Abstract (en)
[origin: EP0959227A2] A method for manufacturing improved pistons (22), which are reciprocated by a swash plate (20) in an compressor. Each piston (22) includes a head (40) and a skirt (42). The head (40) has a cylinder (41) with an open end, and the skirt (42) has a lid (43) for closing the open end of the cylinder (41). The lid (43) is friction welded to the cylinder (41). This method firmly joins the lid (43) to the cylinder (41) and reduces the cost and the time for manufacturing. <IMAGE>
