摘要： PURPOSE:To improve the vacuum degree by opening the atmosphere opened valves installed in the low and high stage gas passages only in the case when the low stage discharge temperature is lower than a set temperature and the high stage discharge temperature is higher than a set temperature. CONSTITUTION:Oil-free screw pumps 1 and 2 are arranged in series, and an opening/closing valve 6 is installed into the branched flow passage 5 between the both pumps 1 and 2. The discharge temperature on the low stage side is detected by a thermocouple 7, and the discharge temperature on the high stage side is detected by a thermocouple 8. When the discharge temperature of the thermocouple 7 is lower than a set temperature which is lower than the max. allowable temperature and the detection temperature of the thermocouple 8 is higher than the max. allowable temperature, the opening/closing valve 6 is opened. Therefore, the both pump stages can be operated in the nearly equal discharge temperature state.

摘要： PURPOSE:To improve the operation efficiency of multistage compressors by changing over pipe lines connecting plural compressor blocks as occasion calls to make it possible to optionally select series or parallel operation of the multistage compressors. CONSTITUTION:In the multistage compressor, the suction side of a low pressure stage compressor block 3 is connected through a control valve 15 to the suction side of a high pressure stage compressor block 5. On the other hand, the delivery side of the low pressure stage compressor block 3 is connected through control valves 16, 17 to the delivery and suction sides of the high pressure stage compressor block 5. Consequently, both the above compressor blocks can be optionally operated in series or parallel by properly changing over the control valves 15, 16, 17.

摘要： PURPOSE: To lower the operational cost of a scroll-type compressor by forming vanes movable pursuant to movement of a revolving scroll on both sides of a suction hole and controlling the movement of the vanes electrically and mechanically.
CONSTITUTION: On both sides of a suction hole 10 formed at the peripheral part of a fixed scroll 1, vanes 19a, 19b with the same height as laps 1a, 2a are formed and made to touch on the wall surface of the lap 2a of a revolving scroll 2. The vanes 19a, 19b are connected with electromagnets 22a, 22b through connecting bars 21a, 21b. Accordingly, a compressor allowing its non-stage performance control in accordance with load only through manipulation of the vane movement is obtained.

摘要： PURPOSE:To allow highly efficient operation by connecting a first air compressor having a larger capacity with a second air compressor having a smaller capacity in parallel relation thereto as a compression source, and controllably operating the first air compressor when flow rate is more than a predetermined value, while operating the second air compressor when less than the predetermined value, on the basis of a detection signal from a detecting means for detecting an amount of air to be supplied from the compression source to a load. CONSTITUTION:A main compressor 1A and an auxiliary compressor 1B are connected with each other. In operation of the main compressor 1A, when compressed air pressure is detected by a lower limit pressure detecting means 4L at the time of T0 as being a lower limit pressure set value, the main compressor 1A starts compression operation. Then, when compressed air pressure is detected by an upper limit pressure detecting means 4mu as being an upper limit pressure set value, the main compressor 1A starts uncompression operation. However, in the case that the pressure is gently reduced, a timer in an operation control device 5 is operated from the time when the pressure reaches the upper limit pressure set value, and if the pressure does not reach the lower limit pressure set value within a period of elapsed time te, an operational contactor 3A for the main compressor 1A is opened at the time of T2 to change control of the operation control device 5, so as to allow the auxiliary compressor 1B to be operated.
摘要翻译：目的：通过将具有较大容量的第一空气压缩机与具有与其平行关系的较小容量的第二空气压缩机作为压缩源连接来实现高效率的操作，并且当流量大于预定值时可控地操作第一空气压缩机根据来自检测装置的检测信号，当检测到从压缩源向负载供给的空气量时，在小于预定值的情况下操作第二空气压缩机。构成：主压缩机1A和辅助压缩机1B相互连接。在主压缩机1A的运转中，当在下一压力检测装置4L中将压缩空气压力作为下限压力设定值进行检测时，主压缩机1A开始压缩运转。然后，当通过上限压力检测装置4mu检测压缩空气压力作为上限压力设定值时，主压缩机1A开始解压缩操作。然而，在压力缓慢降低的情况下，从压力达到上限压力设定值的时刻起，操作控制装置5中的定时器被操作，并且如果压力未达到下限压力设定值经过时间te，在T2时间打开用于主压缩机1A的操作接触器3A，以改变操作控制装置5的控制，以便使辅助压缩机1B工作。

摘要： PURPOSE:To separate completely adjacent compressive elements from each other for running a compressor under capacity control by providing a clutch between crankshafts of the adjacent compressive elements of a plurality of said elements provided axially. CONSTITUTION:When a second compressive element 4 is separated and only a first one 3 is run, a motor 2 is stopped and current to an electromagnetic coil 19 is cut. Thus, a first engaging clutch plate 17 of a clutch 5 is damagnetized and a second engaging clutch plate 18 is dropped by its own weight so that the engagement of engaging claws 17a, 18a of first and second engaging clutch plates 17, 18 is released and crankshafts 7, 12 of first and second compressive elements 3, 4 are separated from each other. Under this condition, a motor 2 is driven so that only the first compressive element 3 carries out the gas compressing action.
