摘要:
A variable capacity type viscous heater is provided which can carry out the capacity control reliably, and which can inhibit the endurable heat-generating efficiency of a viscous fluid from deteriorating even after a long period of service. For instance, its rear housing 6 is provided with a control chamber 9 which is communicated with a central region of a heat-generating chamber 7, and which has an internal volume capable of expanding and contracting. When a rotor 14 is kept rotated, a silicone oil held, in the heat-generating chamber 7, expands the internal volume of the control chamber 9 by the Weissenberg effect in the capacity reduction. As a result, the heating is relieved, because the silicone oil, held in the heat-generating chamber 7, is collected into the control chamber 9.

A heat generating apparatus having a housing assembly in which a working chamber including a heat generating region for heat generation and a fluid storing region for storing a viscous fluid, and a heat receiving chamber for receiving heat from the heat generating region are formed. The heat generating apparatus also having a rotor element mounted on a drive shaft to be rotated within the working chamber to apply a shearing action to the viscous fluid within the heat generating region. The viscous fluid generates heat when the shearing action is applied thereto so that the heat is transmitted to a heat exchanging liquid flowing through the heat receiving chamber. The heat generating region and fluid storing region communicating through an aperture formed in a partition wall formed in the working chamber, and the aperture having a gas-phase portion, a liquid-phase portion and a liquid supply portion.

A compressor mounted on a vehicle is disclosed. The compressor includes an apparatus for transmitting rotational power from an engine to drive shaft of the compressor via a pulley. The apparatus has a spring coupled to one of the pulley and the drive shaft. A deformable ring is coupled to the other one of the pulley and the drive shaft. The deformable ring is deformed by heat. The spring and the deformable ring are being held in abutment against each other by the force of the spring so as to transmit the rotational power to each other. A contact ring is interposed between the spring and the deformable ring. The contact ring has a rigidity larger than that of the deformable ring. The spring and the contact ring frictionally contact one another to generate the heat that deform the deformable ring when load generated in the drive shaft is in excess of a predetermined value.

A heating apparatus for a vehicle with a simplified piping structure in a fluid pressure operating system, to a heat exchanger while preventing a pulsation of the operating fluid in the system from being directly transmitted to a cabin, thereby suppressing an occurrence of a noise in the cabin. A fluid pressure operating system includes an oil pump 12 rotated by an engine 21 and an actuator 20 operated by the operating fluid issued from the oil pump 12. A heat exchanger 39 is arranged between an outlet of the oil pump 12 and the actuator 20. Heat generated at the oil pump 12 in the fluid pressure operating system 11 is passed to the engine cooling water at the heat emitter and is used for heating the cabin.

A heating system for a vehicle is provided which does not require a large boarding space in an engine room very much, which can be manufactured at a reduced cost, and which can fully heat a passenger compartment of a vehicle when an engine is started. For instance, in the vehicle heating system, a water pump (WP) and a viscous heater (VH) is incorporated into an installation housing (1), a plate (2) and a cover (3) which are bonded to a cylinder block of an engine. The water pump (WP) and the viscous heater (VH) are driven by a drive shaft (11) which is shared by them. Moreover, the viscous heater (VH) includes an auxiliary water jacket (WJ.sub.2). The auxiliary water jacket (WJ.sub.2) is communicated with a main water jacket (WJ.sub.1) of the engine by way of a pump chamber (4) of the water pump (WP), and is further communicated with a heater core for heating a passenger compartment of a vehicle.

A viscous heater is provided which can securely inhibit a viscous fluid from leaking even after extended use. For instance, the heater is provided with a shaft-sealing apparatus which seals a driving shaft between a heat-generating chamber and a bearing apparatus. The shaft-sealing apparatus is arranged so that it is cooled by a front water jacket which is disposed adjacent to it.

This invention provides a viscous heater which can attain an improvement in heat generating efficiency while preventing leakage caused by expansion of a viscous fluid. For this purpose, a disk-shaped rotor is employed, and a front housing body, a front plate, a rear plate, and a rear housing body constitute housings, and these are stacked and fastened together by through bolts. Surplus spaces in the shape of concaves are formed in the front plate between the respective through bolts and water passages so as to communicate with the heat generating chamber in their outer circumference.

A viscous fluid type heat generator including a housing assembly in which a fluid-tight heat generating chamber confining therein a viscous fluid to which a shearing action is applied by a disc-like rotor element rotated by a drive shaft, and having inner wall surfaces confronting outer surfaces of the rotor element, the inner wall surfaces of the fluid-tight heat generating chamber and the outer faces of the rotor element defining a gap in which the viscous fluid is held, the rotor element being provided with one or more through-holes formed in an outer peripheral portion and a radially inner portion thereof with respect to the axis of rotation of the rotor element so that the through-holes cooperate with one or more non-circumferentially extending elongate indentations provided in the inner wall surfaces of the fluid-tight heat generating chamber during the rotation of the rotor element to expand a heat generating region formed by the gap. The expansion of the heat generating region formed by the gap increases a restraint acting against movement of the viscous fluid caused by the rotation of the rotor element so as to increase friction and a shearing force acting on the viscous fluid, and heat generation by the viscous fluid is increased.

A viscous heater is provided which can carry out full heat exchange securely. For instance, fins 2c through 2f are formed in a housing, and project into a water jacket RW. Thus, a surface area of a wall surface constituting the water jacket RW is enlarged, and a circulating fluid, taken in through a water inlet port 8 and delivered out to an external heating circuit through a water outlet port 9, is circulated along a specific route.
