Abstract

A motor-pump unit is held in suspension within a hermetic housing by means of helical springs whose ends are attached to the housing and to the motor-pump unit. At least one element (10, 20) is provided for absorbing high frequency vibratory energy, being attached to each helical spring and in close contact with at least part of the surface of the spring wire, along a portion of the latter, in order to absorb and damp the resonances of longitudinal propagation of the waves throughout the spring, without changing the elasticity characteristics of the spring at low frequencies. The element can be a core or sleeve of soft rubber which may be pressed against the surface of the helical spring. An alternative element is a rubber coating or a closely wound coil surrounding the wire of the helical spring.
