Abstract
A coupling device (30) for connecting the armature (16) of an electric motor (10) to a piston (26) of a pump assembly (20) comprises an input member (32) which rotates and imparts the rotation to an output member (34), with a resilient member (36) disposed between the input member (32) and output member (36) to prevent the transmission of noise-generating vibrations between the electric motor (10) and pump assembly (20). The input and output members (32, 34) have respective axially extending projections (44, 46) circumferentially spaced-apart from each other and fingers (52) of the resilient member (36) extend radially into spacings between the projections (44, 46) in order to transmit rotation of the input member (32) to the output member (34) without permitting transmission of noisegenerating vibrations therebetween.
