HEATER UTILIZING FLUID FRICTIONAL HEAT

摘要

A heater utilizing fluid frictional heat according to this invention has a structure suitable for realizing the heater in an elongated shape which is capable of being mounted laterally on an automobile engine. A cylindrical shear applying portion being integral with a drive shaft and having an outer circumferential surface in cylindrical form is disposed in a heat generating chamber formed as a cylindrical space. The shear applying portion is machined with the same support arbors as used in machining the drive shaft. Preferably, the drive shaft and the shear applying portion are machined as a one-piece member made of a single rod-like material.
