A switching valve (10) is described, in particular for metering a fluid for a downstream arranged delivery pump (2), with a flow channel (20), an axially movable valve needle (14), a valve element (16) which can be actuated by the valve needle (14) in an o...

The pump (1) has a pump piston (20) reciprocating in a cylinder bore (18) of a pump cylinder (19) that is sealed by a pump cylinder head (23). A pumping workspace (13) is defined in the cylinder bore by the pump piston and the cylinder head. The pumping wo...

A variable-flow high-pressure pump (1) comprising at least one piston (4) mounted to slide axially and in a leak-tight manner within a cylindrical cavity (5) obtained in the body (6) of the pump so as to define a variable-volume pumping chamber (7) adapted...

The variable volumetric flow device has a first component (1) with an inlet opening (5) coupled to an inlet (4) and a second coaxial component with at least 2 outlet openings (6a,6b) lying in a common plane, each connected to an outlet coupled to the pump....
