[0009] FIG. 3: cross section thru piston and cylinder liner, equipped with permanent magnets;

[0010] Is described an example of the invention with reference to FIGS. 1-3, which represent: The horizontal compressor gas piston compressor includes: a crankcase (29) in which a crankshaft (28) is mounted, a connecting rod (27) fixed to a crosshead (26) thru a bolt (25) which alternately drives in a cross-head body (23) a piston rod (7) into some distance pieces (22 and 21) and a cylinder body (8). The separation of the oil from the crankcase is done through an oil wiper case (24) and the gas sealing of the compression chamber is made thru an auxiliary gas packing (20) and a main gas packing (1). Suction and discharge of the compressed gas is made thru some valves (14 and 18) which are fixed in some valve covers (15 and 19). A cylinder compressor (8) which contain a cylindrical liner (6) in which, rectilinear and alternatively moving an improved piston (11) equipped with some guiding bushings (5 and 12) provided with straight ends and inclined compression chambers (k) and (m) with same angle and in the same plane as the area (n) of a cylinder head element(32) mounted on a cylinder head (17) and the zone (p) of a cylinder head element(33) mounted on a cylinder head (2), through which a piston (11) is free lifting on the stroke length. A piston (11) is mounted on a piston rod (8) thru an piston nut (13) and is equipped with some rider rings (10) arranged in some channels of a piston (11) to assure the mounting of a piston (11) and a piston rod (7) without direct contact with a cylinder liner (6) and some piston segments (9) located in some channels of a piston (11) for gas compression and sealing of a piston (11) into a cylinder (8), along the length of the stroke.
