Lucas CAV DPA and Minimec fuel pulsation damper (early type)

£28.75

Item 37 in the exploded diagram. Please check the image is correct for your pump as there are variants to these depending on your application.

Description

This is the damper for older DPA and Minimec pumps commonly fitted to Fiat, Allis Chalmers, New Holland, Ford Cargo engines

The later type damper is available HERE

Dampers are sometimes fitted to certain injection pump fuel outlet galleries. The circular metal diaphragm form of damper is is connected by screwed union to the injection pump gallery.
Following injection of fuel, when the pump ends the injection phase, the high pressure fuel can be released back into the pump. This release causes an increase in gallery pressure but is followed by a rapid fall in pressure.
This pressure increase after injection may be high enough to lift the delivery valve off its seat, i.e. when by-pass delivery valves are fitted high peak pressures cause increased fuel delivery.
The object of the damper is to prevent the gallery pressure rising too high and to prevent it falling too low.
When injection ends and fuel spills back into the gallery, the metal diaphragm of the damper deflects to increase the effective gallery volume. This volume increase reduces the peak pressure. When the diaphragm moves back towards its original position, the gallery pressure is prevented from falling too low.

Fits the following DPA pumps:
