Abstract
A reciprocating pump comprising several pumping volumes formed by cylinders fixed to a frame in an axial piston arrangement, and by pistons capable of sliding in the cylinders under the action of a driving mechanism, and including a ducting assembly conveying the liquid to be displaced from a general intake conduit to the pumping volumes, through intake valves, and from the pumping volumes to a general delivery conduit, through delivery valves. The ducting assembly comprises both a central cylinder head through which passes a central distribution channel connected to the general intake conduit and supplying off-take passages which radiate around it to the side bearing surfaces, and side cylinder heads through which run passages conveying the liquid.
