Patent ID: 8402760

Claim:
A vibration-decoupling device for hydraulics comprising: a fluid transfer element ( 3 ) of tubular form with a first end ( 4 ) and a second end ( 5 ), the first end ( 4 ) being suitable for being connected with a high pressure outlet of a hydraulic pump ( 1 ) for transporting fluid expelled therefrom, a fixed element ( 11 ), being a frame or a housing which is suitable for resisting mechanical vibrations and pulsations of the fluid caused by operation of the hydraulic pump ( 1 ), second end ( 5 ) of the fluid transfer element ( 3 ) is moveably connected within fixed element ( 11 ) to allow movement of the transfer element ( 3 ) in an axial direction and in at least one direction orthogonal to the axial direction so that fluid can be passed to a hydraulic consumer, and a support element ( 9 ) of tubular form is moveably connected with the fixed element ( 11 ) and the fluid transfer element ( 3 ) to allow movement of the support element ( 9 ) and transfer element ( 3 ) in an axial direction and in at least one direction orthogonal to the axial direction and acts so that a supporting force is exerted on the fluid transfer element ( 3 ) in one direction while the second end ( 5 ) of the fluid transfer element ( 3 ) and the fixed element ( 11 ) remain securely connected together.
