The utility model provides a rolling rotor formula compressor, its main constitution has: motor element, casing subassembly, pump body subassembly. As shown in fig. 11 and 12, the motor assembly includes a motor stator and a rotor, the housing assembly mainly includes an upper cover, a housing, a lower cover, an exhaust pipe, an intake pipe, a terminal, and a bolt, and the pump assembly mainly includes a crankshaft, an upper flange, a cylinder, a lower flange cover, a roller, a rotating portion 52, a blocking portion 52, a valve plate, and a sliding piece 42. The variable volume structure of the cylinder exhaust port 2 comprises a crankshaft 8, a cylinder, a roller 6, a sliding vane 42, a blocking part, a rotating part 52, a pin and the like, and can realize that the displacement of the sliding vane 42 can be changed within a certain range, and the displacement of the blocking part 52 can be changed along with the pressure difference of the front end and the rear end of the blocking part 52 and the action of the rotating part 52.

The operation principle of the compressor of the embodiment is as follows: the low-temperature and low-pressure refrigerant from the evaporator enters the shell through the shell air suction pipe and then enters the cylinder through the air cylinder air suction pipe on the upper part of the shell and the upper flange air suction port 7. The crankshaft 8 is driven by the motor rotor to synchronously rotate, and the roller 6 on the eccentric part of the crankshaft 8 also runs along with the crankshaft. As shown in fig. 4, the inner wall of the cylinder body 1 and the outer wall of the roller 6 form a compression chamber, the compression chamber is divided into a high-pressure chamber and a suction chamber, namely a low-pressure chamber, under the action of the sliding vane 42, the gas sucked by the low-pressure chamber is compressed to high temperature and high pressure, then is discharged to the lower flange cavity, and then enters the condenser through the lower flange exhaust port, so that the whole refrigeration cycle is realized in the refrigeration system.

Referring to fig. 1, the cylinder slide groove is 0 °, the rotation direction of the crankshaft 8 is a positive direction, the distance between the head of the blocking portion 32 and the inner circle of the cylinder is H, the H is the maximum value H, and the included angle between the side edge of the adjusting groove 31 and the slide 42 is β. When the pump body crankshaft 8 rotates to drive the roller 6 to move, the slide sheet 42 moves along with the roller, and the blocking part 32 reciprocates under the action of the slide sheet 42 and the pressure difference between the head part and the tail part of the blocking part 32.

Fig. 1 shows the starting position of the crankshaft 8, where θ is the rotation angle of the crankshaft 8, i.e., θ is the rotation angle of the crankshaft 8 equal to 0 °. Referring to fig. 10 in combination, the specific process is as follows:

when theta is more than 0 degree and less than or equal to a, the sliding sheet 42 acts on the rotating part 52, so that the head part of the blocking part 32 is superposed with the inner circle of the cylinder body 1, at the moment, H is 0mm, the volume of the exhaust port of the cylinder body 1 is the minimum, and the air suction port 7 of the cylinder body 1 is communicated with the exhaust port;

when a is larger than theta and is smaller than or equal to b, the sliding sheet 42 moves towards the center of the circle of the cylinder body 1, the pressure of a compression cavity of the cylinder body 1 is larger than the pressure in a shell, the blocking part 32 is far away from the inner circle of the cylinder body 1, H is gradually increased to H, and namely the volume of an exhaust port of the cylinder body 1 is gradually increased to the maximum;

when b is larger than theta and is smaller than or equal to c, because the pressure of the compression cavity of the cylinder body 1 is larger than the pressure in the shell, H is always kept equal to H, namely the volume of the exhaust port of the cylinder body 1 is kept maximum;

when c is more than theta and is less than or equal to 360 degrees and a, the sliding sheet 42 is abutted against the rotating part 52, so that the rotating part 52 rotates to drive the plugging part 32 to move towards the inner circle of the cylinder body 1, H is gradually reduced to 0 from H, namely, the volume of the exhaust port of the cylinder body 1 is reduced to the minimum from the maximum, and at the moment, the air suction port 7 and the exhaust port of the cylinder body 1 are not communicated;

when the angle is more than 360 degrees and more than a and less than 360 degrees, because the sliding sheet 42 always abuts against the rotating part 52, H is 0 and keeps unchanged, namely the volume of the exhaust port of the cylinder body 1 keeps minimum, and at the moment, the air suction port 7 of the cylinder body 1 is communicated with the exhaust port.

Wherein, the relation among each angle is: a is more than or equal to beta, b is more than a, and c is more than or equal to 360-b. The clearance volume of the exhaust port 2 on the cylinder body 1 is changed along with the cycle of the crankshaft 8 by one cycle, when the clearance volume of the exhaust port 2 is communicated with the suction port 7, the clearance volume of the exhaust port 2 is minimum, and when the clearance volume of the exhaust port 2 is not communicated with the suction port 7, the clearance volume of the exhaust port 2 is kept maximum or is reduced from maximum to minimum.

Further, the rotation portion 52 is hinged to the blocking portion 32.

Referring to fig. 8, a stopper table is disposed on a surface of the tail portion of the sliding piece 42 close to the communicating groove 51, and the stopper table is used for shifting the rotating portion 51, so that one end of the rotating portion 52 moves towards an inner circle direction of the cylinder body 1, and the other end of the rotating portion 52 moves towards an outer circle direction of the cylinder body 1, and further drives the blocking portion 32 to move towards an outer periphery side of the cylinder body 1, so as to increase the exhaust port 2.

The rotating portion 52 is hinged to the blocking portion 32 through a hinge structure, and the displacement H of the blocking portion 32 is changed as the sliding piece 42 is displaced.

When the rotation angle theta of the crankshaft 8 is increased from a to 180 degrees, the distance of the sliding sheet 42 extending out of the sliding sheet groove 41 is increased to the maximum, and at the moment, under the action of the stop table of the sliding sheet 42, the displacement H of the blocking part is increased from 0 to the maximum H;

when c is more than theta and is less than or equal to 360 degrees and a, the sliding sheet 42 is abutted against the rotating part 52, so that the rotating part 52 rotates to drive the plugging part 32 to move towards the inner circle of the cylinder body 1, H is gradually reduced to 0 from H, namely the volume of the exhaust port of the cylinder body 1 is reduced to the minimum from the maximum, and at the moment, the air suction port 7 is not communicated with the exhaust port 2;

when the angle is 360-a < theta < 360 degrees, H is 0 and keeps unchanged because the sliding sheet 42 always abuts against the rotating part 52, namely the volume of the exhaust port 2 keeps minimum, and the air inlet 7 of the cylinder body 1 is communicated with the exhaust port 2.
