摘要： A positive displacement roots blower can include a housing having an inlet structured to receive an incoming flow of a fluid, an outlet structured to receive an outgoing flow of the fluid, and a passage. The positive displacement roots blower can also include a pair of intermeshed rotating members supported for complementary rotation within the housing, where the rotating members and the housing form respective operating volumes there between which rotate with the rotating members. Each of the respective operating volumes has the following regions: (1) open to inlet/closed to outlet; (2) closed to inlet/closed to outlet; and (3) closed to inlet/open to outlet. The passage includes a restriction and connects to at least one of the operating volumes when the at least one of the respective operating volumes is in region (2). The restriction can be a venturi feedback connecting to the outlet.

摘要： A compressor includes a casing, a compression mechanism, and a motor that drives the compression mechanism. The casing is configured to cover an internal space. The internal space includes a first space and a second space larger than the first space. The casing has a first casing part covering the first space and a second casing part covering the second space. At least one of the first space and the second space is a high-pressure space configured to contain high-pressure fluid. A metallic coating may be formed on an outer surface of at least the first casing part. Alternatively, a resin coating may be formed on an outer surface of the casing.

摘要： An attachment structure is for attaching a compressor to an attachment surface of an attachment target member. The compressor is a scroll type compressor and has a housing, a fixed scroll and a movable scroll. The housing is fixed to the attachment surface. The fixed scroll is fixed inside the housing and has a fixed-side tooth having a scroll shape. The movable scroll has a movable-side tooth having a scroll shape and engaging with the fixed-side tooth. The movable scroll revolves with respect to the fixed scroll. A central axis around which the movable scroll revolves is parallel with the attachment surface. A vibration direction, which is included in a radial direction of the compressor and in which a vibration component becomes largest, is different from a normal direction when viewed in an axial direction of the central axis.

摘要： A fluid machine includes a motor and a motor housing. The motor housing defines a motor chamber for accommodating the motor. The motor chamber is filled with inert gas. A rotor rotates in accordance with rotation of the motor. A pump housing defines a pump chamber for accommodating the rotor. A dividing wall is located between the pump housing and the motor housing. The pump housing and the motor housing are attached to each other via the dividing wall. Therefore, water is prevented from being generated in the motor chamber even if fluid that contains hydrogen leaks from the pump chamber to the motor chamber.

摘要： A vacuum pump has a housing and a pump mechanism accommodated in the housing. An exhaust-passage forming portion is located outside of the housing. The exhaust-passage forming portion forms an exhaust passage, which exhaust passage guides gas discharged from the pump mechanism toward the outside of the vacuum pump. A thermal conductor is connected to the outer surface of the exhaust-passage forming portion. The thermal conductor is made of a material having a thermal conductance of which is greater than that of the material for the exhaust-passage forming portion.

摘要： Application of a positive displacement pump to the pumping of helium at very low temperatures. Positive displacement pumps, formed from mobile components (35, 36), which deliver gas volumes to pumping chambers, have the advantage of operating under satisfactory conditions for significant temperature, pressure and gas flow rate variations. They are therefore preferred as compared with the hitherto used centrifugal pumps and have means enabling them to operate at very low temperatures.

摘要： A pneumatic system which in the preferred embodiment includes a pump having a primary suction port and a secondary suction port, with the pump being operable for generating vacuum pressures at both such ports. A first vacuum operated system is coupled to the primary suction port and a second vacuum operated system is coupled to the secondary suction port, and a predetermined, preferably selectively adjustable, orifice is established between the first and second vacuum operated systems for enabling vacuum airflow generated at the first suction port to augment the airflow through the second vacuum operated system. In an alternative embodiment, separate standard vacuum pumps are coupled to the first and second vacuum operated systems.
