Abstract
A support of an intank pump at a pump support, which includes webs of elastic material that extend from the pump to the pump support in a direction deviating at an angle .alpha. from the radial which is determined by the longitudinal axis of the fuel pump. During swelling of the webs by the fuel, a rotary movement is thereby imparted to the pump without influencing the suction height. The webs may thereby have a relatively large volume as a result of which a good damping is achieved.
Claims17
A mounting arrangement for an electrically driven fuel pump which is immersible in fuel in a fuel tank, said mounting arrangement comprising:
- pump support means fixedly disposable in a fuel tank,
- and a plurality of damping web means of substantially equal length and extendable from outer circumferential portions of a pump to said support means to support the pump in position on the support means, said damping web means all extending at approximately the same angle with respect to respective radii extending from a longitudinal axis of a fuel pump being supported thereby to respective support connections of radial outer ends of the damping web means at the pump support means, whereby expansion movements of the damping web means are accommodated by rotational movement of a pump being supported about its longitudinal axis without substantially changing its axial position.
