摘要： In one embodiment of the present invention, a water pump (10) is configured such that rotation is transmitted in a non-contact condition from a drive-end rotation member (20) whereto rotation is transmitted from an engine to a driven-end rotation member (30) having a pump impeller (31). The drive-end rotation member (20) includes a vacuum chamber (50) and a pair of permanent magnets (26a, 26b) provided so as to be mutually opposed with different polarities. The driven-end rotation member (30) includes an induction ring (32) having an induction section (32b) provided so as to form a prescribed interval between the pair of permanent magnets (26a, 26b). Furthermore, the pair of permanent magnets (26a, 26b) is moved in a rotation axis direction with respect to the induction section (32b) due to the vacuum introduced into the vacuum chamber (50), and the overlap amount (L1) of the pair of permanent magnets (26a, 26b) and the induction section (32b) in the rotation axis direction is changed.

摘要： A pulley is fixed to a housing of a water pump, the pulley being connected to an output shaft of an internal combustion engine so that the pulley is driven through the output shaft. In the housing, a slider moves to and fro due to a change in pressure in a pressure chamber, which causes the magnetic flux passing through a magnet and an inductor ring of a rotary cylinder to vary, so that the driving force of the internal combustion engine is variably transmitted to the rotary cylinder. The pressure chamber is connected to an intake air passage and an atmospheric air introducing portion through a pressure path, and the state of communication is changed by a VSV. The pressure passage is provided with an orifice for preventing rapid change in pressure in the pressure chamber when the VSV is switched.

摘要： A water pump is driven by a driving force generated by an internal combustion engine, and generates a larger driving force as a pressure introduced into a pressure chamber becomes higher. The pressure chamber is connected to a VSV through a first passage. A portion of an intake passage, which is located downstream of a throttle valve, is connected to the VSV through a second passage. An atmospheric pressure space is connected to the VSV through a third passage. In the VSV, the volume of wax in a temperature-sensitive case is increased to increase the ratio of the cross sectional area of an opening portion of the third passage, which is connected to the first passage, to the cross sectional area of an opening portion of the second passage, which is connected to the first passage, as the temperature of a coolant for the internal combustion engine increases.
