  • Publication number: 20240092316
    Abstract: A cleaning device for cleaning a see-through area of an environment sensor of a motor vehicle and for determining an operating-pressure-dependent functional state of at least one cleaning nozzle, the cleaning device having the at least one cleaning nozzle, which is configured to dispense a cleaning fluid. The at least one cleaning nozzle may have a pressure sensor configured to assume at least one position as a function of an operating pressure of the cleaning fluid at the cleaning nozzle and thus determine an operating-pressure-dependent functional state of the at least one cleaning nozzle, in particular as at least one measuring signal.

  • Patent number: 8020896
    Abstract: A hose connector (19, 59) for the assembly in a housing opening (13) of a tank of a portable handheld work apparatus is formed as one piece and has a base plate (20). A sealing rim (21) for mounting in the housing opening (13) is provided on the base plate (20) at a first side (57). The hose connector (19, 59) has at least one connecting channel (31, 32) which projects through the base plate (20) and which, at least at one end, has at least one connecting stub (24, 24?, 25, 26, 26?) for connecting to a hose line. A first connecting stub (26, 26?) is fixed within the sealing rim (21) on the base plate (20) and has a pull-off protector (54). The pull-off protector (54) is at a distance (e) to the base plate (20) perpendicularly to the plane of the base plate (20) which is greater than the distance (f) of the lower edge (51) of the sealing rim (21) to the base plate (20). The lower edge (51) faces away from the base plate (20).

  • Patent number: 6446421
    Abstract: A hedge trimmer has a tool that is driven by a drive unit. At least one vibration-dampened handle is secured to the drive unit. The handle comprises a one-piece component having a grip portion and a mounting portion for mounting on the drive unit. To simplify mounting of the handle, the grip portion and the mounting portion are interconnected by a vibration-dampening intermediate portion. The mounting portion along with the intermediate portion and the grip portion form the one-piece or monolithic component.
