摘要： A flow control device for constraining fluid flow between axial flow turbomachines in series has a flow constrainer which constrains the fluid flow downstream of the first turbomachine in the series to the blades region of the second turbomachine, preventing fluid flow from impacting the hub or nosecone of the second turbomachine and providing more uniform fluid flow to the second turbomachine. The flow control device includes connective elements for positioning between the downstream region of the first turbomachine and the upstream region of the second turbomachine. The device may be equipped with stator vanes having a variety of optional configurations to further improve the uniformity of the fluid flow load on the second turbomachine.

摘要： A single-tube blowing suction device, including a body, an airflow generation apparatus, a collection apparatus, and a blowing-suction tube. The airflow generation apparatus has an air inlet portion and an air outlet portion and is rotatably mounted on the body. The airflow generation apparatus rotates relative to the body to enable the single-tube blowing suction device to switch between a suction mode and a blowing mode. In the suction mode, the air inlet portion is in fluid communication with a first end of the blowing-suction tube, and the air outlet portion is in fluid communication with a connection port of the collection apparatus. In the blowing mode, the air outlet portion is in fluid communication with the first end of the blowing-suction tube. In the single-tube blowing suction device of the present invention, one tube is used for both blowing and suction.

摘要： A vehicle heater includes a heater housing (12′), through which heating air to be heated can flow, with a heating air inlet area and with a heating air outlet area. A burner unit is arranged in the heater housing. A combustion air blower (46′) is arranged in the heater housing for delivering combustion air to the burner unit. A heat exchanger unit is arranged in the heater housing (12′). Heating air flowing through the heater housing (12′) can flow around the heat exchanger unit. A combustion air intake muffler (76) is arranged essentially in the heater housing (12′). A muffler housing (78) made in one piece with the heater housing (12′) is associated with the combustion air blower (46′).
