摘要： A viscous fluid shear device that includes a floating wiper. The wiper defines at least one fluid channel on a surface of the wiper that faces a circumferentially extending surface on a rotor. Each fluid channel has a first portion, which is formed with a first cross-sectional area, and a second portion that is formed with a second, smaller cross-sectional area. Each of the first and second cross-sectional areas is defined by first and second planes, respectively, that extend through the central axis. The second plane is spaced circumferentially apart from the first plane in the predetermined rotational direction.

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： A clutch device for a clutch system has an input member that rotates at a first speed. A friction drive system is disposed between the input member and an output member. The clutch device is selectively movable by a fluid actuator assembly, between an engaged position in which the friction drive system drives the output member to rotate at the first speed, and a disengaged position in which a viscous drive system rotates the output member at a second speed slower than the first speed. A variable viscous fluid supply assembly includes a viscous fluid storage chamber, a valve, and a valve actuator that selectively drives the valve to move between an open position and a closed position to control an amount of viscous fluid available to the viscous drive system, thereby varying the second speed.

摘要： A fluid coupling device (15) is disclosed of the type including an output coupling assembly (67) and an input coupling member (81) with a shear space (90) disposed therebetween. The coupling device includes a valve assembly (117) to control the flow of fluid from a reservoir chamber (99) into the shear space (90). Movement of the valve assembly (117) is in response to variations in air pressure in a pressure chamber (59), tending to bias a piston (57) and shaft (93) in opposition to the force of a spring (113). Axial movement of the shaft (93) is translated into movement of a valve arm (127) in a plane parallel to the plane of a fluid port (119) by means of a valve actuation mechanism (109). In the subject embodiment, axial movement of a valve actuation piston (111) results in rotation of the valve assembly (117) about the axis of rotation of the device (15) for improved valve action in a remote sensing type of fluid coupling device.

摘要： A fluid friction clutch especially for powering a rotary cooling fan for an internal combustion engine. The clutch has a driven part with a drive disc rotating in a drive chamber which is separated from a fluid reservoir chamber by a separating wall within the clutch housing. A passage in the separating wall can be opened and closed by a valve assembly which is actuated by a temperature-dependent element. The temperature-dependent element is an expansion element containing a substance which undergoes volume changes as a function of temperature. The expansion element is heated electrically by means of a PTC resistor under the control of a thermal switch which reacts to engine-related temperatures. When the power supply to the PTC heater is interrupted, the clutch engages and provides full cooling power.

摘要： The invention provides a pneumatic control system for a pneumatically operated clutch in the drive to a cooling fan of a vehicle engine. There are two thermostat valves arranged in series in the pneumatic control line. One valve is positioned in the supercharged air passage and the other valve is in the liquid coolant passage. If the temperature at either valve becomes excessive the supply line 22 is connected to relief and the fan clutch automatically engages.

摘要： A pressure-responsive fluid-shear coupling for an automobile engine fan. The pressure increase with increasing temperature of a circulating liquid coolant in the cooling system acts directly against a bellows. The bellows in turn controls the flow of a silicone fluid and the degree of coupling between the engine and the fan.

摘要： A device that employs shear forces to transmit energy includes an outer housing assembly, a disk, and a reservoir with a working fluid. The disk is received in and rotatable relative to the outer housing assembly. A working cavity is formed between a rotor portion of the disk and the outer housing assembly into which the working fluid is received to create shear forces. A plurality of flow altering structures are disposed on the outer housing assembly and are configured to reduce a thickness of a boundary layer of the working fluid in the working cavity in areas that are local to the flow altering structures.
