Abstract: A resilient element connects the housing of the spindle collar bearing with the spindle rail and contains a circumferential arrangement of resiliently flexible rods surrounding with play the housing of the spindle collar bearing in a substantially parallel relationship thereto. The resiliently flexible rods which are arranged at substantially uniform circumferential spacing from one another extend at both of their ends from an associated common retaining sleeve for the related rod ends. One such retaining sleeve is anchored at the spindle rail. The other retaining sleeve is fixedly anchored at the housing of the spindle collar bearing in a region or at a location spaced from a housing side at which the spindle exits from such housing. The resilient element forms a spatial parallelogram permitting only radial movement of the housing against the spring action of the resiliently flexible rods without inclined positioning of the housing.

Abstract: An elastic support system is disclosed for a fuel system of motor vehicles of the type equipped with a mixture-compressing internal-combustion engine and an electrically driven fuel pump, a fuel filter and an accumulator, in which case at least the fuel pump is to be arranged in proximity of the tank at the underbody. A roller vane pump is used as the fuel pump which operates with heavy pulsations and therefore, in addition to its mechanically caused operating noises, also generates pulsation noises. It therefore must be disconnected or isolated from the underbody with respect to vibrations. For this purpose, it is suggested by the invention to provide, between the fuel pump and a suspension member fastened at the underbody of the motor vehicle, a connecting element that is held at the fuel pump and can be suspended at the suspension member.

The metal stirrup (2) is provided such that it at least partially encloses the outer mount part (6) of the spring element (4).

Abstract: A well servicing system in which sonic energy is transmitted down a pipe string to a down hole work area a substantial distance below the surface.

The cylinder is suspended from a suitable suspension means such as a derrick, with the pipe string being suspended from the cylinder in an in-line relationship therewith. The fluid in the cylinder affords compliant loading for the piston while the fluid provides sufficiently high pressure to handle the load of the pipe string and any pulling force thereon. The sonic energy is coupled to the pipe string in a longitudinal vibration mode which tends to maintain this energy along the string.

A first member which attaches to the wall or a strip of plumbers tape extending between the studs is attached to the body at the first location. A second member which attaches to the plumbing components is attached to the body at the second location. The first and second members are connected to the body at their respective locations such that a parallel portion of the first member is parallel with, but is not coplanar with, a parallel portion of the second member.

A strip bracket is adapted to be fixed at one end portion to the exhaust system and inserted at its other end portion parallel to and between the opposite side walls of the U-shaped channel bracket so as to form two spaces between the other end portion of the strip bracket and each of the side walls of the U-shaped channel bracket. Two vibration absorbing members are inserted into the spaces, respectively, and firmly joined to the side walls of the U-shaped channel bracket and the other end portion of the strip bracket to prevent the transmission of vibration of the exhaust system to the vehicle body. There is a spacing between the other end portion of the strip bracket and the bottom of the U-shaped channel bracket thereby preventing the transmission of vertical vibrations from the strip bracket to the U-shaped channel bracket.
