Abstract

1,204,943. Free piston machines. H. BENAROYA. May 22, 1968 [May 24, 1967], No.24502/68. Headings F1B and F1Q. A free piston machine which may be a free piston compressor or gas generator comprises two aligned drive cylinders 1 1 , 1 2 , in each of which work two opposed drive pistons 2 1 , 3 1 , 2 2 , 3 2 , the inner drive pistons 2 1 , 2 2 , working respectively in one and the other of these two drive cylinders being mechanically inter-connected thus forming a first group, the two outer drive pistons 3 1 , 3 2 , which also work respectively in one and the other of the two drive cylinders being mechanically inter-connected, thus forming a second group and the mechanical connection means of this latter group comprising at least one conjugation rod 8 which is parallel to the axis of the machine and is located externally of the drive cylinders synchronization means is provided between the two groups so that when the two opposed drive pistons which work in one of the drive cylinders perform their outward stroke (work stroke) the two opposed pistons which work in the other drive cylinder perform their inward stroke (compression stroke). Each of the outer drive pistons is connected to a compensator piston 27 2 working in a fixed compensator cylinder 26 2 and operable to compress air in the compensator cylinder during the inward movement of one of the outer drive pistons thereby creating in the fixed compensator cylinder a resistance to the movement during the inward stroke of the corresponding outer drive piston in order to avoid the presence of compression stresses in the conjugation rod or rods A number of modications are described. Compensator cylinders may be arranged around a compressor cylinder with their axes parallel to the axis of an engine cylinder.
