<p>PURPOSE:To improve the safety, reliability and durability in control by installing a suction passage for introducing coolant into a suction chamber and installing a throttle valve device in the suction passage. CONSTITUTION:In a throttle valve device 19 installed in a suction passage 14a leading to a suction chamber 14, the pressure in the suction passage 14a is detected by a bellows 23, and the position of a valve body 24 is changed for an opening 21 according to the magnitude of the pressure, and control is performed so that the pressure in the suction passage 14 becomes nearly constant. When the pressure in the suction chamber 14 lowers, the gas compression reaction force reduces, and the action point approaches a pin 5b, and the moment for increasing the tilt angle of a swash plate 6 reduces, and the tilt angle of the swash plate 6 reduces, and the capacity of the compressor reduces. On the contrary, when the pressure in the suction chamber 14 lowers, the tilt angle of the swash plate increases, and the capacity of the compressor increases.</p> |
