Device for conserving cavities in automobile body, has reducer provided in area of connection for strongly reducing cross section of line of specific length, where reducer is fixed in connection by press fit, sticking, or welding process

摘要

The device (1) has nozzles (4), where wax is applied on inner walls of a cavity which is to be conserved over the nozzles. The nozzles are attached to a compressed air line and to a wax line over a connection (5). A reducer is provided in an area of the connection for strongly reducing the cross section of a line of about 1.5 mm. The reducer reduces the cross section of the line as conical-shape. The reducer is fixed in the connection by press fit, sticking, soldering or welding process. The device is fastened by an automobile body over a holder (6).
