摘要： The invention relates to an axial fan, in particular for radiators of motor vehicles, the axial blades being fastened to a fan hub, and the fan hub in turn being connected to a viscous fluid friction clutch. According to the invention, air-guide elements or guide blades are arranged in the hub region on the front side or suction side of the axial fan. These air-guide elements or guide blades deflect the flow from the front side to the rear side of the blades and thereby stabilize the flow. To further improve the flow conditions, the hub region is covered by a cap on its front side. The cooling-air flow on the front side of the viscous fluid friction clutch and the hub flow of the fan are stabilized by the air-guide elements in combination with the

摘要： The present invention improves both the quality and the flow of air delivered by a stationary fan such as a ceiling fan and a portable fan. Ceiling fans provide limited indoor air flow, but do not function as air conditioning and quality improvement apparatus. The present invention provides fans with an ability to increase indoor and outdoor air quality where they operate. One or a combination of a cooling unit and a heating unit and a filtering device and a secondary multidirectional fan provide consumers with air quality improvement options for stationary and portable fans to fulfill their specific needs for a given area.

摘要： A process fluid recycle system for compressor assemblies to recycle process fluid vapor flowing from one or more compressors to gear case(s) through shaft seal(s). The flowing process fluid is recycled back to the low pressure inlet of the compressor assembly by way of a recycle conduit. Coalescing filters are provided to separate oil mist from the process fluid vapor. Oil vapor and water vapor can also be removed, where necessary, by suitable oil and water vapor traps. During startup and shutdown or other times when low pressure transients occur that could cause a back flow of gear oil from the gear case into the compressor(s) by way of the shaft seal(s), an anti-back flow compressor is operated to ensure that the pressure within the gear case will be less than within the compressor.

摘要： A composite rotor is provided having a main body portion and a plurality of circumferentially spaced blades extending radially from the body portion. The rotor also includes a plurality of recessed radial splines in the body portion thereof. The splines are adapted for engaging a coupler, such as a gearwheel, and transmitting torque thereto. The amount of shear area provided by the recessed splines for transmitting torque from the rotor to the coupler is significantly increased over conventional designs because the shear area includes not only area in the inter-laminar plane, but also in the cross-laminar plane.

摘要： An engine cooling system include a ring-type cooling fan (10) that includes a central hub (12), a plurality of blades (11) projecting radially from the hub (12) and an outer circumferential ring (15) connected to the blade tips (17). In one aspect of the invention, the outer ring (15) includes a flared rim (28) at the outlet side (10b) of the fan (10) that improves the stackability and stability of multiple fans. In another aspect of the invention, each of the blades (11) includes a support vane (30) defined on the rear face (25) of the blade (11). The support vane (30) is curved to follow the curvature of the airflow (F) across the back (25) of the fan blades (11). Each support vane (30) originates at the blade root (19) and terminates at the trailing edge (11b) of the blade in the first half of the blade length. The support vanes (30) provide first mode stiffness for the fan (10). In certain embodiments, a support ring (35) is defined at the central hub (12) inboard of the support vanes (30). A vane support superstructure (37) is configured between the support vanes (30) and the support ring (35) to react the aerodynamic loads experienced by the support vanes (30). A further support superstructure (37) can be configured between the support ring (35) and the central hub (12). Other features of the invention provide a stress-reducing blend region (20) between the blade tips (17) and the flared rim (28) of the outer ring (15), and an improved blade geometry.

摘要： A circulator pump-motor unit which has an impeller assembly that can selectively tilt between two positions is disclosed. Each of the two positions corresponds to aligning a suction port with one of two inlet ports. The unit can be used to, for example, change the path of hot water conveyed between these ports so that either a hot water system or a hydronic system gets heat.
