Abstract: A inject gas control device that performs, for example, control reflecting variation in vessel velocity over time without adversely affecting the main engine is realized. That is, it is prevented that gas is drawn too much and thereby a gas supply or charged air rate becomes insufficient, efficiency of the main engine is decreased and exhaust gas is deteriorated, and analogous events occur because the gas supply or charged air rate is too much instead. There are provided a main engine 4010 acquiring propelling power for a vessel 1, and a turbocharger 4011 that is driven by exhaust gas from the main engine 4010 and blows pressurized gas to the main engine 4010. A part of the pressurized gas and/or exhaust gas is drawn from between the turbocharger 4011 and the main engine 4010 (5023, 5024 and 5025).

Abstract: A lead wire of a motor is prevented from being damaged, and the reliability of an electric compressor is enhanced. The electric compressor 1 is provided with a division wall 80b which divides a discharge chamber 62 and a connection space 65 which connects a sealed terminal 90 and a lead wire 5c of a motor 5. With this configuration, it is possible to prevent discharge gas from directly flowing into the connection space 65, and to prevent the discharge gas from flowing into a wire passage 64 through which the lead wire 5c is passed. Therefore, vibration of lead wire 5c caused by gas pulse can be suppressed, the lead wire can be prevented from being damaged, and the reliability of the electric compressor can be enhanced.

Abstract: It is an object of the present invention to make an oil-reservoir chamber independent from a motor chamber into which a refrigerant compressed by a compressor mechanism is introduced, thereby reducing a compressor in size. In a compressor 1, a partition member 7 is provided in a housing 3 on the opposite side from a compressor mechanism 4 with respect to a motor 5. The partition member 7 is pushed by a stator 5a of the motor 5, thereby liquid-tightly fixing the partition member 7 to the housing 3. The oil-reservoir chamber 6 is formed independently from a motor chamber 2 in which the motor 5 is accommodated, and lubricant oil is efficiently separated from a refrigerant with a simple structure.

Abstract: Lubricating liquid fed from a reservoir to a compression mechanism is collected by a circumferential wall that surrounds the drive shaft of the compression mechanism and rotates synchronously with it immediately after liquid is discharged into the space inside the housing with or without compressed fluid. Liquid is then urged outward under centrifugal force from an outlet formed at a preset axial location of the circumferential wall. Exiting liquid is received by a fixed liquid return cover that surrounds the circumferential wall near its outlet and led back to the reservoir.
