<p>The device for metering flow media has a closed housing (10) with an inlet (24) and outlet (26) channel for the media to be metered. A movable section formed by a piston (20) creates two chambers (16, 18) of variable volume within the housing. A distributor block (14) of rotatable or vibratory motion is connected to the inlet (24) and outlet (26) wall sections and has channels (22, 28) which connect the in (24) and outlet (26) channels to the chambers (16, 18) of the housing(10) in an alternating manner according to the rotational position of the distributor block (14).</p> |
