Rotary slant shaft type gas compressor with multi-stepped exhaust system

A rotary slant shaft type gas compressor comprising:

• a driving shaft integrally formed with a cylinder head perpendicular to the driving shaft, the cylinder head being formed with a plurality of gas holes on a concentric circle at uniform intervals;
• a gas guide member formed with an intake manifold for intake of gas from the outside and an exhaust manifold for discharging gas compressed in cylinder bores to the outside;
• a case head member for rotatably supporting the driving shaft formed with at least one intake port for supplying the gas taken in through the intake manifold to the inside of the cylinder bores, and two or more exhaust ports for discharging the gas compressed in the cylinder bores to the exhaust manifold;
• a valve plate member fixed on an inner surface of the case head member to contact an outer surface of the cylinder head, and formed with a gas intake valve groove and at least two gas exhaust valve grooves on a periphery on which the gas holes move, the gas intake valve groove supplying the gas taken in through the intake port to the inside of the cylinder bores and the gas exhaust valve grooves discharging the gas compressed in the cylinder bores to the exhaust ports;
• a cylinder block formed with a plurality of cylinder bores in parallel with the driving shaft and having a surface integrally coupled with the cylinder head, and having an opposite surface slidably inserted with pistons in respective cylinder bores for compressing the intake gas in the respective cylinder bores;
• a swivel plate member connected to a center part of the cylinder block with a coupling, and connected to a plurality of pistons via piston rods, for converting a rotation force transmitted from the driving shaft to rectilinear reciprocation motion to be transmitted to the pistons;
• a case end plate formed with a slant surface for supporting the swivel plate member;
• and
• a case coupled with the case head member and the case end plate for incorporating the cylinder block and the swivel plate member.
