摘要： A fan assembly includes an annular nozzle and a system for creating a primary air flow. The nozzle includes an outer wall and an inner wall surrounded by the outer wall, the inner wall defining a bore having a bore axis. The nozzle also includes an interior passage located between the inner and outer walls, and extending about the bore axis for receiving an air flow, and an air outlet located at or towards the front of the nozzle for emitting the air flow. The nozzle is configured to emit the air flow through the air outlet in a direction extending away from the bore axis.

摘要： An ejector includes a nozzle, a swirl flow generation portion, a body including a refrigerant suction port and a diffuser portion, a passage forming member, and an actuation device moving the passage forming member. A nozzle passage is defined between the nozzle and the passage forming member. A smallest passage cross-sectional area portion is provided in the nozzle passage. A swirl space that has a shape of a revolution and is coaxial with the nozzle, and a refrigerant inflow passage through which the refrigerant flows into the swirl space are defined in the swirl flow generation portion. The ejector further includes an area adjustment device that changes the passage cross-sectional area of the refrigerant inflow passage. According to this, an efficiency of energy conversion in the nozzle passage can be improved.

摘要： An ejector has a nozzle, a body, a passage defining member and a drive portion. The body has a refrigerant suction port and a pressure increasing portion. A nozzle passage is defined between an inner surface of the nozzle and an outer surface of the passage defining member and has a minimum sectional area portion, a tapered portion, and an expansion portion. The minimum sectional area portion has a smallest passage sectional area. The tapered portion is located upstream of the minimum sectional area portion in a refrigerant flow direction and has a passage sectional area decreasing toward the minimum sectional area portion gradually. The expansion portion is located downstream of the minimum sectional area portion in the refrigerant flow direction and has a passage sectional area increasing gradually. The passage defining member has a groove that is recessed to increase the passage sectional area of the nozzle passage.

摘要： An assembly for controlling the eductive dispensing of multiple chemical fluids is described. The assembly is designed to detachably engage with existing eductor valve assemblies as either an original part or as a replacement part. The assembly comprises a plurality of selector gears that rotatably engage with eductor valve assemblies. The selector gears are in communication with a control gear. When the assembly is attached to a plurality of eductor valve assemblies an individual can control the rotation of multiple valve assemblies by rotating a single control knob.

摘要： A mixing portion that mixes an injection refrigerant and a suction refrigerant is formed in a range of an internal space of a heating-side body portion of a heating-side ejector from a refrigerant injection port of a heating-side nozzle portion to an inlet of a heating-side diffuser. Further, the mixing portion is formed in a shape that gradually decreases a refrigerant passage area toward a downstream side of a refrigerant flow, and a refrigerant passage area of the inlet of the heating-side diffuser is set smaller than that of the refrigerant injection port. Thus, the flow velocity of the mixed refrigerant is decelerated to a value lower than a two phase sound velocity within the mixing portion, thereby suppressing occurrence of shock wave in the heating-side diffuser and stabilizing the pressure increasing performance in the heating-side diffuser.

摘要： A quick-release vacuum pump which is mainly applied to a vacuum transport system. The vacuum pump has a mechanism in which part of compressed air supplied for generating a vacuum state is stored firstly in a chamber, and then the vacuum state within the chamber is released when transportation is completed. When the vacuum state is released, a check valve is moved by the pressure of air that flows backward. The range of movement of the check valve is adjusted by a control means. An air filter is disposed at the lower end of the check valve. The release of the vacuum state is quick and controllable. Also, the filter is naturally filtered and cleaned.
