摘要

#CMT# #/CMT# The carrier (4) has a frame comprising an exhaust cleaning device coupled with a housing for longitudinal passage of a spring (13). The frame is mounted on an engine, where the engine rotates a drum. An input receives a flexible tube from the drum. An operating mechanism adjusts force with which rollers (71, 72) act against a spring button. The housing comprises rotating parts whose portion is connected to the frame. The rollers are positioned in the frame, where a state of the rollers is changed by rotating one of the rotating parts of the housing. #CMT#USE : #/CMT# Spring Carrier for a drain cleaning machine (claimed). #CMT#ADVANTAGE : #/CMT# The carrier varies movement direction and movement speed of the tube without changing rotation speed of the engine. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a longitudinal sectional view of a spring carrier. 4 : Spring carrier 13 : Spring 71, 72 : Rollers 75 : Passage opening 84, 85 : Projections.
