摘要:
A regenerative blower includes an annular housing assembly that surrounds a rotating impeller and defines a toroidal flow channel, an inlet to admit fluid to the toroidal flow channel, an outlet to discharge fluid from the toroidal flow channel, a low fluid-pressure region of the toroidal flow channel proximate to the inlet, and a high fluid-pressure region of the toroidal flow channel proximate to the outlet. A non-contact interaction between concentric surface contours of the impeller and the housing assembly form opposed concentric fluid pathways between the impeller and the housing assembly from the high to low fluid-pressure regions of the toroidal flow channel. The opposed concentric fluid pathways are so convoluted as to restrict fluid from flowing therethrough from the high fluid-pressure region of the toroidal flow channel to the low fluid-pressure region of the toroidal flow channel.

The invention relates to a rotary compressor that includes a disc-shaped rotor having a radius R, supporting on the periphery thereof at least one first series of non-planar blades intended for accelerating the fluid to be compressed between an intake and an outlet, a casing defining on the outside at least one generally toroidal channel that is peripheral to the rotor, said at least one channel being coaxial, arranged at the radial end of said rotor and containing said blades, a static and annular core being arranged inside said at least one toroidal channel such as to define a free section A with said casing. According to the invention, the arrangements and respective shapes of the rotor, the at least one peripheral channel and said at least one series of blades are such that the ratio A/R2 is between 6% and 16%.

摘要:
The invention relates to a conducting unit for gas, comprising a compressor (101) in a soundproof housing (20, 40) that is provided with an intake port (27, 66) and a blow-off port (24, 69, 70). An intake tube (96) can connect the intake port to the inlet of the compressor while a discharge tube (96) can connect the blow-off port to the outlet of the compressor. A sound absorber (60, 80) encompassing an inlet chamber (73, 97) and an outlet chamber (74, 98) can be accommodated in the soundproof housing. The internal walls of the soundproof housing can be lined with neoprene while metal sheets (131, 133) can be mounted between the soundproof housing and the compressor. An internal cooling member (42) and an internal fan (48, 49) can cool the compressor. A cooling member (41) can form one side (40) of the soundproof housing. An external fan (7) can cool the cooling member. Blind tubes can be used at the inlet and the outlet for absorbing tonal noise. The invention further relates to corresponding conducting methods.
