摘要： Noise attenuation units are disclosed that are connectable in a system as part of a fluid flow path. Such units include a housing defining an internal cavity and having a first port and a second port each connectable to a fluid flow path and in fluid communication with one another through the internal cavity, and a noise attenuating member seated in the internal cavity of the housing within the flow of the fluid communication between the first port and the second port. The noise attenuating member enables the fluid communication between the first port and the second port to flow through the noise attenuating member.

摘要： An engine system having a compressor coupled to an engine and supplying air to an intake manifold, a throttle controlling the supply of air from the compressor to the intake manifold, a compressor recirculation valve (CRV) having a pneumatic control chamber, and a throttle aspirator having its motive section in fluid communication with an inlet of the throttle and its discharge section in fluid communication with an outlet of the throttle and its suction port in fluid communication with the pneumatic control chamber of the CRV. Such an engine system automatically minimizes surge during boost without a control system activating the CRV. Here, the CRV operates purely on the changes in pressure within the system forming a loop that resets itself. In another embodiment, a gate valve and a vacuum canister may be included rather than having the throttle aspirator directly connected to the CRV's pneumatic control chamber.
摘要翻译：一种发动机系统，其具有联接到发动机并将空气供给到进气歧管的压缩机，控制从压缩机向进气歧管供应空气的节气门，具有气动控制室的压缩机再循环阀（CRV）和节气门吸气器其动力部分与节气门的入口流体连通，并且其排放部分与节气门的出口及其吸入口流体连通，与CRV的气动控制室流体连通。这样的发动机系统在升压期间自动最小化浪涌，而不需要启动CRV的控制系统。在这里，CRV完全基于系统内的压力变化，形成一个重置自身的循环。在另一个实施例中，可以包括闸阀和真空罐，而不是使节气门吸气器直接连接到CRV的气动控制室。

摘要： An aspirator for creating vacuum is disclosed that includes a housing defining a fluid passageway with a first tapering portion and a second tapering portion. Each tapering portion has a larger internal opening and a smaller internal opening, the smaller openings facing one another. The aspirator includes a gate positioned between and in fluid communication with the first and second tapering portions, the gate having a first Venturi tube with a Venturi opening creating vacuum when fluid flows in a direction and a second Venturi tube with a Venturi opening that creates vacuum when fluid flows in the opposite direction. The Venturi openings are in fluid communication with a suction port, and the first and second Venturi tubes may provide different mass flow rates through the aspirator. An engine system having an aspirator with a gate having a first bore and a second bore and an actuator is also disclosed.
