A compressor to compress liquid or gaseous fluids comprising a cylinder with a plunger provided therein. In a first embodiment, on both sides of said plunger, respective fluid suction and compression chambers are defined. On the longitudinally opposite ends of the compressor, respective fluid suction and discharge valves are provided. The plunger is connected to pulling means extending along the cylinder and projecting out of the compressor to cause the longitudinal reciprocating motion of the plunger by pulling said pulling means. In a second embodiment of the invention, on one side of the plunger a fluid suction and compression chamber is defined, and in one first end of the cylinder adjacent to said suction and compression chamber, a valve head is fixed with housings for the fluid suction valves and fluid discharge valves. The compressor plunger is connected, on one side, to pulling means projecting out of the cylinder to manually operate the compressor, and on the other side to elastically deformable pulling means extending between the plunger and a second end of the cylinder. Said pulling means are capable of elastically expanding and they allow for the advance of the plunger to effect the compression and discharge of the fluid, and are also capable of contracting to force the retreat of the plunger and allow for the suction of the fluid into the fluid suction and compression chamber.
