摘要： A valve assembly for a viscous clutch includes an orifice plate defining a bore to allow the passage of a fluid through the orifice plate, a reed valve secured relative to the orifice plate, an armature comprising a magnetic flux-conducting material, an anchor spring secured to the armature, and a stiffening plate. The reed valve includes a tongue configured to selectively cover the bore of the orifice plate, and a first pivot location along the tongue. A second pivot location is defined along the anchor spring at an edge of the stiffening plate. The first and second pivot locations are spaced from each other. The armature is configured to selectively apply a force to the reed valve to pivot at least a portion of the tongue about the first pivot location.

摘要： A viscous clutch (20) includes a housing assembly (28), a rotor assembly (26), a reservoir (38) to hold a supply of a shear fluid, a working chamber (40) operatively positioned between the housing assembly and the rotor assembly, and a fluid return bore (26- 1B) that optionally extends radially through at least an outer diameter portion of the rotor assembly to the working chamber. Selective introduction of the shear fluid to the working chamber facilitates selective torque transmission between the housing assembly and the rotor assembly. The fluid return bore can form at least a portion of a fluid return path (50) from the working chamber to the reservoir.

摘要： A viscous clutch (20; 20') includes a rotor (26), a housing (24) that at least partially surrounds the rotor, a center shaft (22) rotationally fixed to the housing, a mounting disk (30) rotationally fixed to the rotor, a working chamber (38) defined between the rotor and the housing, a reservoir (36) for holding a supply of shear fluid, an electromagnet (34), a valve assembly (32) to selectively control flow of the shear fluid between the reservoir and the working chamber, and a flux guide (54) operatively positioned between the electromagnet and the armature. At least a portion of the mounting disk extends outside the housing. The valve assembly including an armature (32-3) that is selectively movable in response to magnetic flux generated by the electromagnet, and the magnetic flux is transmitted between the armature and the electromagnet along a flux circuit. The flux guide extends through the mounting disk.

摘要： Un embrague viscoso (30; 30´) incluye una abrazadera fija de articulación (32; 32´) que define un eje de montaje (32-1; 32-1´), un miembro de salida (34; 34´) soportado, en forma giratoria, en el eje de montaje alrededor de un eje (A), un miembro de entrada (34; 34´) soportado, en forma giratoria, en el eje de montaje alrededor del eje, y una cámara de trabajo (50; 50´) definida entre el miembro de entrada y el miembro de salida para transmitir, de manera selectiva, el torque entre los mismos cuando está presente un fluido transversal. El eje de montaje se extiende en dirección axial a través del embrague viscoso de la cara frontal (62; 62´) del embrague viscoso a la cara posterior (56; 56´) del embrague viscoso, con la cara posterior que define una superficie de montaje para el montaje del embrague viscoso en una ubicación de montaje. Las caras frontal y posterior se localizan en los lados opuestos del embrague viscoso y se orientan en las direcciones opuestas.

摘要： A viscous clutch includes a rotor, a housing member, a working chamber located between the housing member and the rotor, a reservoir to hold viscous fluid that is configured to rotate with the rotor, a return bore in fluid communication between the working chamber and the reservoir, a first passage from the reservoir to the working chamber, a second passage from the reservoir to the working chamber, and a valve. The second passage is spaced from the first passage, and can extend substantially radially through the rotor. The valve is configured to selectively regulate flow of the viscous fluid through the first passage, and the second passage is unobstructed such that the viscous fluid can pass from the reservoir to the working chamber regardless of the operational state of the valve. Viscous fluid present in the working chamber rotationally couples the rotor and the housing member.

摘要： Un embrague con acoplamiento viscoso (30) incluye un rotor (36), un elemento de carcasa (38), una cámara de trabajo (50) situada entre el elemento de carcasa y el rotor, un depósito (48) para mantener el fluido viscoso que está configurado para girar con el rotor, un orificio de retorno (64) en comunicación de fluido entre la cámara de trabajo y el depósito, un primer pasaje (66) desde el depósito hasta la cámara de trabajo, un segundo pasaje (82) desde el depósito hasta la cámara de trabajo, y una válvula (40). El segundo pasaje está separado del primer pasaje, y se puede extender sustancialmente de forma radial a través del rotor. La válvula está configurada para regular selectivamente el flujo del fluido viscoso a través del primer pasaje, y el segundo pasaje no está obstruido, de tal manera que el fluido viscoso puede pasar desde el depósito hasta la cámara de trabajo, independientemente del estado operacional de la válvula. El fluido viscoso presente en la cámara de trabajo acopla rotacionalmente el rotor y el elemento de carcasa.

摘要： A viscous clutch (30; 30') includes a stationary journal bracket (32; 32') defining a mounting shaft (32-1; 32-1'), an output member (34; 34') rotatably supported on the mounting shaft about an axis (A), an input member (34; 34') rotatably supported on the mounting shaft about the axis, and a working chamber (50; 50') defined between the input member and the output member to selectively transmit torque there between when a shear fluid is present. The mounting shaft extends axially through the viscous clutch from a front face (62; 62') of the viscous clutch to a rear face (56; 56') of the viscous clutch, with the rear face defining a mounting surface for mounting the viscous clutch at a mounting location. The front and rear faces are located at opposite sides of the viscous clutch and face in opposite directions.
