Abstract (en)
[origin: US5330331A] A metering pump for highly viscous fillings has a crankshaft-type drive for a back-and-forth movement of a piston (1) in a cylinder (2) and a drive for a forward-and-backward rotational movement of a rotary slide valve (4) derived from this. The rotary slide valve (4) has openings and the housing of said rotary slide valve has connections for a suction line (7) and a discharge line (8) for the piston/cylinder unit (1, 2). A plate cam, coupling assembly (14) and clamping lever (25) engaging with the turntable (4) are provided for the rotational movement of the rotary slide valve (4). The coupling assembly (14) has a pivoted lever (20) having an articulated joint (21) formed on one end which in turn is formed on a bearing block (19), arranged locally fixed and slideable. An adjusting drive (30) for altering the position of the bearing block (19) is provided independent from the crankshaft-type drive.
