Title:
VISCOUS HEATER
Document Type and Number:
WIPO Patent Application WO/1998/008699
Kind Code:
A1
Abstract:
A viscous heater which is capable of preventing the interference of an outer surface of a rotor with a wall surface of a heating chamber while keeping adequate that generation per revolution of the rotor. To form such a viscous heater, restriction portions (1a, 2a) are provided as interference preventing means so as to annularly protect in the opposed direction on an inner circumferential region of a rear end surface of a front housing (1) which defines a heating chamber (7), and on an inner circumferential region of a front end surface of a rear plate (2) which defines the heating chamber (7). The interference preventing means may also be provided by forming the rear end surface of the front housing (1), which defines the heating chamber (7), and the front end surface of the rear plate (2) which defines the heating chamber (7), outwardly divergently in cross section to form clearances on the outer circumferential regions of these end surfaces.
