Embodiment Construction

[0039] An advantageous embodiment of a suction hose fitting according to the invention, generally designated 10 , is shown schematically in the drawing. The suction hose fitting 10 has a housing 12 with a first housing part 14 , a second housing part 16 and a third housing part 18 . The first housing part 14 forms the front side 20 of the housing 12 and the second housing part 16 forms the rear side 22 of the housing 12 . The third housing part 18 can be screwed onto the second housing part 16 and protrudes with a rear end section 24 beyond the rear side 22 of the housing 12 .

[0040] The first housing part 14 forms a filter device in the form of a filter cage 28 with a plurality of housing openings 30 with a front housing section 26 adjoining the front side 20 , which housing openings are respectively located on two sides. Adjacent partitions 32 extend between them. The housing opening 30 forms overall an inlet opening 34 of the housing 12 .

Abstract

The invention relates to a suction hose fitting (10) for connection to the suction hose of a high-pressure cleaning device, having a housing (12) which has an inlet opening (34) and an outlet opening (104), wherein a filter device (28) is arranged at the inlet opening (34) and a connection device (44, 48) for the suction hose is arranged at the outlet opening (104), and wherein a non-return valve, which closes in the direction of the inlet opening (34) and has a valve body (90) which can be moved to and fro between a closed position and an open position in the housing (12), is arranged in the housing (12). In order to develop the suction hose fitting in such a way that cleaning of the filter device (28) can be simplified, it is proposed according to the invention that the non-return valve can be manually released.

Description

technical field [0001] The invention relates to a suction hose fitting for connection to a suction hose of a high-pressure cleaner, with a housing having an inlet opening and an outlet opening, wherein a filter device is arranged at the inlet opening, and A coupling device for the suction hose is arranged at the outlet opening, and wherein a non-return valve closing in the direction of the inlet opening is arranged in the housing, the non-return valve having a valve body in the housing Can be moved back and forth between a closed position and an open position. Background technique [0002] This suction hose fitting is used in the suction hose of a high-pressure cleaner. With the aid of a high-pressure cleaner, the liquid, preferably water, is pressurized and then discharged via a pressure hose. For example, nozzles or cleaning lances can be arranged at the free end of the pressure hose, by means of which the liquid pressurized by the high-pressure cleaner can be aimed at t...
