A fluid compressing apparatus including a cylinder block having a cylinder
bore with a diameter penetrating through the cylinder block in a
lengthwise direction, a discharge chamber having a diameter larger than
the diameter of the cylinder bore, and at least one fluid suction port
penetrating into the cylinder block including an interconnected space
comprising a fluid discharge port. A piston serves to open and close the
suction port while linearly reciprocating within the cylinder bore
eliminating need for a separate suction valve assembly. A valve plate
separates from and opens the discharge port as a result of the high
pressure of the fluid in the cylinder bore, thus compressing the fluid
until completely discharged; such that the clearance volume in the
cylinder bore is minimized improving compression efficiency.
