Abstract
A compressor having a rotor, a cylinder rotatably accommodating the rotor, vanes slidably mounted on the rotor, side plates secured to both sides of the cylinder so as to close both open ends of cylinder chambers defined by the cylinder, rotor and the vanes, a suction port and a discharge port for a refrigerant, and a temperature-sensitive valve disposed in the passage communicating with the suction port and adapted to open and partially close the suction port. Representing the rotating angle of the rotor between the position at the beginning of the suction stroke and the position at completion of the suction stroke by .theta..sub.s rad., the volume of the cylinder chamber at the position of completion of the suction stroke by Vo cc, and the effective area of the suction passage between the evaporator and the cylinder chamber in the opening state of the temperature-sensitive valve by a.sub.2 (.theta.) cm.sup.2 ; the means value a.sub.2 of the effective area is given as follows: ##EQU1## Similarly, the mean value a.sub.1 of the same effective area a.sub.1 (.theta.) cm.sup.2 in the state where the temperature-sensitive valve is operating is given as follows: ##EQU2## The compressor i…
