Claims

[Claims for Utility Model Registration] An upper gas inlet 12 is provided at a selected position around the cylinder 11, a rotor 3 is installed eccentrically at the lower part of the cylinder to avoid the gas inlet, and the rotor 3 is installed at a selected position around the cylinder 11, a plurality of slots spaced apart in the radial direction, each slot having a notch located near the front outer end of the slot in the direction of rotation of the rotor, the motor being connected to the rotor; a vane 33 is slidably mounted in each of said slots, each vane being slidable outwardly against the inner surface of said cylinder; a gas chamber is defined between the blades and by the outer surface of the rotor and the inner surface of the cylinder; an end plate 13 is fixed to the cylinder to seal it; the end plate has an arcuate shape; The end plate has a groove 15 in the shape of a boss and is located in a position covered by the end face of the rotor, the arc-shaped groove is in the passage of the notch of rotation of the rotor, and the end plate has a boss cavity.
) 2, the center of which coincides with the center of rotation of the rotor, and the end plate includes an unloading passage communicating with the cavity and an unloading passage.
) is provided in communication with the cavity, an expelling passage is in communication with the cavity, and the passage is located around the cavity; a sliding ring 4 is provided in communication with the cavity;
), a sliding ring is fixed against rotation with respect to said end plate, said sliding ring has a discharge hole 42, and said sliding ring has a discharge hole 42; passes through one shaft end of the unloading hole.
g hole) 43 passes through the opposite shaft end of the sliding ring, and further includes one evacuation hole (exp
elling hole) 41 is of sufficient size and always communicates with the arc-shaped groove regardless of the axial position of the sliding ring, and the evacuation hole always communicates with the arc-shaped groove regardless of the axial position of the sliding ring. Exhaust passage and 10
0% overlap, and the axial position of the sliding ring allows the discharge hole and the discharge passage (d
ischarge password) is 0 and 1
00%, and depending on the axial position of the sliding ring, the unopened hole (unlo
adding hole) is the above-mentioned unactuated passage (un).
loading passage) from 100% to 0%, and when the discharge passage overlaps the discharge hole by 0%, the unused passage overlaps the unused hole by 100%; It is connected to the rotor, extends outward from the rotation center of the rotor, makes sliding contact with the inner surface of the sliding ring, and has a groove around the shaft end, which communicates with the hole of the sliding ring. having four slots with four vanes, said arc-shaped groove having a length slightly greater than 90°; each said passageway having a length in said end plate; at least partially extending radially; the motor is an electric motor; the expelling hole
) extends in the axial direction, and each of said discharging and unlo
adding holes) are circular,
Rotary compressor.
