  • Publication number: 20160221172
    Abstract: A hand-held power tool is disclosed. The hand-held power tool has a drive and a pneumatic percussive mechanism. The percussive mechanism has a hammer movable along a working axis, a driving piston bound to the drive by a connecting rod, and a pneumatic chamber that couples a movement of the hammer to the driving piston. The connecting rod is suspended from the driving piston so as to swivel about a swiveling axis. A sealing ring encloses in a plane a lateral surface of the driving piston. The swiveling axis lies in the plane.

  • Patent number: 7084374
    Abstract: A heating flange especially for the preheating of the intake air of an internal combustion engine with a frame (8), a supporting ceramic element (2) with a heating band (10) fitted thereto. The supporting ceramic element 2 is held in the frame at an inner side of the frame, and a support spring (1) is arranged between the supporting ceramic element (2) and the inner side of the frame. The support spring (1) is a leaf spring which is straight in the non-stressed state, and sits under an initial prestess between the supporting ceramic element (2) and the inner side of the frame. As a result of this configuration, low friction arises between the supporting ceramic element (2) and heating band (10), as well as leaf spring (1), which reduces failures due to vibratory loading, and a defined initial spring tension with a defined spring deflection is produced.
