Abstract
A vacuum nozzle system has a vacuum nozzle with an inlet opening for engaging a surface to be vacuumed and an outlet opening for connection to a vacuum supply hose. The inlet opening is delimited by a circumferential end face. The nozzle defining a vacuum flow direction from the inlet opening to the outlet opening. A holder bracket has a holder for holding the nozzle. The holder is disposed downstream of the end face in a vacuum flow in the vacuum flow direction when the nozzle is in a retained position on the holder bracket.
Claims8
A vacuum nozzle system, comprising:
- a vacuum nozzle having an inlet opening and an outlet opening for connection to a vacuum supply hose, said inlet opening being delimited by a circumferential end face, said end face for engaging a surface to be vacuumed, said nozzle defining a vacuum flow direction from said inlet opening to said outlet opening;
- and a holder bracket having a holder for holding said nozzle, said holder being disposed downstream of said end face in a vacuum flow in the vacuum flow direction when said nozzle is in a retained position on said holder bracket;
- said nozzle having a nozzle inner surface profile taper in the flow direction and said holder having a holder surface profile taper in the flow direction matching said nozzle inner surface profile taper, said taper surface profiles for engaging one another and ensuring a reliable seal of the nozzle to the holder as said nozzle wears over a service life thereof.
A vacuum nozzle system, comprising:
- a vacuum nozzle having an inlet opening and an outlet opening for connection to a vacuum supply hose, said inlet opening being delimited by a circumferential end face, said end face for engaging a surface to be vacuumed, said nozzle defining a vacuum flow direction from said inlet opening to said outlet opening;
- and
- a holder bracket having a holder for holding said nozzle, said holder being disposed downstream of said end face in a vacuum flow in the vacuum flow direction when said nozzle is in a retained position on said holder bracket, said nozzle having an inner wall defining a nozzle surface profile, said holder being constructed as a tongue with a circumferential tongue surface profile matching said nozzle surface profile for sealing said nozzle to said tongue when said nozzle is in the retained position;
- said nozzle surface profile having a taper in the flow direction and said tongue surface profile having a matching taper in the flow direction, said tapers ensuring a reliable seal of the nozzle to the tongue as said nozzle wears over a service life thereof.
