| A liquid injection type scroll compressor is used to a refrigerating apparatus using hydrocarbon fluoride refrigerant which does not contain chlorine (HFC-125/HFC-143a/HFC-134a) as an operating fluid and an amount of an injected liquid is controlled according to a discharge temperature of the compressor. Further, ester oil and/or ether oil is used as refrigerator oil and a dryer is disposed in a refrigerating cycle. With this arrangement, a refrigerating cycle operation can be stably realized in a wide range without almost changing the arrangement of a conventional refrigerating apparatus. | ||||||

| In an automatic transmission, the amount of transmission fluid discharged is controlled by a flow control valve. A fixed displacement type pump is connected with a bypass passage through which a part of fluid discharged from a discharge port of the pump flows back to a suction port of the pump. A flow control valve is provided in the bypass passage so as to regulate the amount of discharged fluid at an approximate equal level according to a feedback pressure generated in a pressure regulating valve. | ||||||

| A method of controlling a fluid compression system having at least one compressor for compressing a fluid medium includes defining the permissible minimum and maximum values of the user line pressure at the point of demand. The user line pressure is continuously monitored using a pressure sensor, and the working pressure of the compressor is monitored. The pressure difference between the working pressure of the compressor and the user line pressure at the point of demand is monitored. The pressure rate-of-change of the fluid medium delivered to the point of demand is monitored, and at least one of the compressors is controlled by a control unit on the basis of at least one of the monitored parameters defined in the foregoing steps of the method. A control system for controlling the operation of at least one compressor uses a plurality of sensors for sensing the status of the flowing medium. | ||||||
| 44 | Compressor assembly with welded IPR valve | US372593 | 1995-01-13 | US5503542A | 1996-04-02 | Walter T. Grassbaugh; Jeffery D. Ramsey |
| A compressor has an hermetic shell within which is located an internal pressure relief (IPR) valve. The valve is resistance welded directly to a separation plate in a scroll compressor or directly to the outside wall of the discharge muffler in a piston/cylinder compressor. The direct welding of the IPR valve eliminates unnecessary components and lowers the manufacturing costs of the compressor. | ||||||

A thermal element is positioned to sense a temperature and is coupled to the sleeve to move the sleeve in response to the sensed temperature. The movement of the sleeve is operable to vary the amount of hot lubricant admitted through the first aperture and to vary the amount of cooled lubricant admitted through the second aperture to control a temperature of the bulk lubricant. | ||||||

An inverter-integrated or an inverter-separated electric compressor has a control device. The control device estimates a compressor suction pressure based on the temperature of the power element of the inverter, or directly measures the compressor suction pressure by a sensor, or estimates the compressor suction pressure based on a compressor suction temperature or on a compressor housing temperature. Further, the control device calculates a motor torque based on a motor rotational speed, a motor phase current, and a motor phase voltage, estimates a compressor discharge pressure based on the compressor suction pressure and the motor torque, and estimates a compressor discharge temperature based on the compressor suction pressure and the compressor discharge pressure. An electric compressor having a discharge temperature detection means in place of a conventional thermal protector can be realized. |

| PURPOSE: To improve work efficiency, to be favorable in reduction of size, and to improve mounting ability when an oil pump device is mounted on a car body. CONSTITUTION: When the number of revolutions of a rotor 2 is low and an oil pressure through a main delivery port 31 is low, the confluent port 74 of a control valve 7 is released. Oil in a first oil passage 61 through a main delivery port 31 and oil in a second oil passage 62 through a subdelivery port 32 are joined together at a confluent area 5T to ensure a necessary oil pressure. Meanwhile, when the number of revolutions of the rotor 2 and an oil pressure through the main delivery port 31 is increased, the valve body 77 of a control valve 7 is moved in a direction B2, the confluent port 74 is closed to block confluence. A second port 72 is communicated with a feedback port 73, and feedback of working oil in the second oil passage 62 through the feedback port 73 to a feedback oil passage 66 is carried out. | ||||||
