Claims

[Claims for Utility Model Registration] (1) A cylinder block with an elliptical inner circumference, front and rear side blocks attached to both sides of the cylinder block, and a cylinder interior constituted by the cylinder block and both side blocks. a rotor that is rotatably suspended horizontally on the rotor and has a plurality of vanes that can move forward and backward in the radial direction;
It consists of approximately disk-shaped front and rear control plates that are disposed on the front and rear end surfaces of the cylinder block and are rotatably connected to each other, and a drive means for the control plates, which control the suction pressure in the suction chamber. Accordingly, by operating the drive means to rotate the front and rear side control plates and continuously move the intake port of the control plate that communicates the communication hole formed in the front side block with the cylinder chamber, A gas compressor characterized in that the capacity of a compression work chamber is variable according to operating conditions. (2) The driving means for the control plate includes a cylinder whose rear end faces the outside and which is movable in the suction chamber, and which is inserted into the cylinder and moves the cylinder toward the suction chamber by a predetermined spring pressure. It consists of a spring that biases the cylinder, a connecting means that connects the cylinder tip and the front control plate, and a connecting means that connects the front control plate and the rear control plate, and the difference between the suction pressure and the spring pressure The cylinder is moved forward and backward by pressure, and as the cylinder advances and retreats, the front control plate is rotated by a predetermined angle, and the rear control plate is rotated by a predetermined angle in conjunction with the front control plate. A gas compressor according to claim 1 of the utility model registration claim.
