Title:
CAPACITY VARIABLE VISCOUS HEATER
Document Type and Number:
WIPO Patent Application WO/1997/010112
Kind Code:
A1
Abstract:
There is provided a capacity variable viscous heater in which its capacity is positively reduced and which prevents reduction in heat generating efficiency after a service life of a long-term use. For instance, a control chamber (9) is disposed in a rear housing (6) that communicates with a central area of a heat generating chamber (7) and in which its internal volume can be increased or decreased. Silicone oil in the heat generating chamber (7) increases the internal volume of the control chamber (9) by virtue of Weissenberg effect when reducing the capacity with a rotor (14) kept rotating. This recovers the silicone oil in the heat generating chamber (7), whereby the heating capacity is reduced.
