HIGH-PRESSURE CLEANING INSTRUMENT AND CLEANING MEASUREMENT

摘要

In the case of a high-pressure cleaning instrument (1), it is proposed to form a flexible portion (7) of a liquid passage (3) between an instrument tip (4) and an operating end (19) in links (8, 9, 10) which are connected to one another in an articulated manner, wherein adjacent links (8, 9, 10) are connected to one another via at least one joint (11, 21) in each case and each have a pressure-application surface (14, 27) on a joint head (15, 24), with which pressure application surface the respective at least one joint (11, 21) is fixed or can be fixed in the liquid passage (3) in a pressure-dependent manner by an internal pressure.

主权项

1. A high-pressure cleaning instrument (1) comprising: a liquid passage (3) which opens outwards at an instrument tip (4) via a nozzle (5), a first link (8) and a second link (9), in which a portion (7) of the liquid passage (3) is formed, said first and second links are connected in an articulated manner to each other via at least one joint (11), the at least one joint (11) has a joint socket (16) and a joint head (15) which is mounted in the joint socket, a pressure-application surface (14) to which an internal pressure in the liquid passage (3) is applied is formed on the joint head (15), and the joint head (15) acts upon the joint socket (16) in a pressure-dependent manner.
