A scroll-type compressor includes a compression-chamber-forming member, a housing, an injection passage part, and a relief mechanism. The compression-chamber-forming member forms a compression chamber and has a movable scroll and a fixed scroll. The housing forms a back pressure chamber. Refrigerant to apply back pressure to the compression-chamber-forming member is accumulated in the back pressure chamber. The injection passage part is linked to the compression chamber. The relief mechanism is configured to establish a communication between the compression chamber and the back pressure chamber communicating when injection pressure of the refrigerant flowing from the injection passage part into the compression chamber is higher than the pressure in the back pressure chamber.

A screw compressor is for use of a screw chiller, and comprises a pair of screw rotors and a casing housing the screw rotors, a capacity control valve for varying a ratio of volume, a motor for driving the screw rotors and an inverter for varying the rotational speed of the motor. The screw compressor is controlled using rotational speed control means by the inverter and mechanical capacity control means by the capacity control valve independently or combined together according to loads. The maximum efficient point in a capacity control performed solely by the inverter is set to a rotational speed side lower than the rated operation point. In a region where the rotational speed is higher than the maximum efficient point, the inverter solely takes control from a rated rotational speed to a high rotational speed side.

19 Control method and device for volumetric flow amount of vacuum pump JP35053897 1997-12-19 JPH10220373A 1998-08-18 CONRAD ARMIN
PROBLEM TO BE SOLVED: To provide a method and a device which can reproducibly set a volumetric flow amount of a vacuum pump and enable adaption to each vacuum process. SOLUTION: A method and a device are provided to obtain advantageous influence in process inside a vacuum chamber. A part of gas flow is returned to a suctioning flange through a connection piping 8 and a control valve 9 in a vacuum pump 1 composed of one or plurality of stages 2a, 2b, 2c. Pressure on the suctioning side is increased, while a volumetric flow amount in respect to gas to be discharged is reduced by means of the pump 1. It is thus possible to accurately and directly control the volumetric flow amount of the vacuum pump 1.
20 Liquid fuel delivery with vapor detection US15932314 2018-02-16 US20180230996A1 2018-08-16 Don Crowder; Grant Davisson; Jeremy Patten
One or more techniques and/or systems are disclosed for providing for improved liquid fuel delivery, by helping to mitigate damage to pumps when operated in an undesired condition. A sensor detects the presence of a liquid fuel at the inlet to the pump during pump operation, and sends the signal to a controller. Based on the detection signal from the sensor, the controller can determine whether a desired amount of liquid is present at the inlet to the pump. If a desired amount of liquid is not identified at the inlet to the pump, the controller may interrupt the power provided by a power supply, which is supplying power to operate the pump, thereby interrupting operation of the pump.
