<p>1. Dosing pump, especially for dosing liquid components of reactive resin compositions, - with a displacer which can be moved forwards and backwards, - an inlet valve (Ev) which is constructed as a disc valve and can be positively controlled from outside, - an outlet valve (Av) which is constructed as a disc valve and can be positively controlled from outside, - the inlet valve (Ev) and outlet valve (Av) having valve stems (VsE, VsA) which run coaxially, characterized in that the valve stems (VsE, VsA) of the inlet valve (Ev) and outlet valve (Av) extend in the same direction in the pump head (Pk) and run telescopically within one another.</p> |
