Title: IP outlines - check valves?
Post by: Gutta Perka on June 07, 2008, 02:32:44 pm

On the back of the IP there are four check valves starting the the injectionlines to the motor.

I have some Boschpumps with different check valves.

Are they fitted to the sprayers?

Can I take a set of these checkvalves and interchange with any other Bosch-IP-pumps checkvalves?

They have no number printed on them so they doesen't seem to be correlated to the sprayers.

If you are talking about the delivery valves on the head you shouldn't really mix and match them

two types: return flow restriction and constant pressure
the first are used on IDIs and the latest on TDIs.
they have springs and shims to allow them to be tailored to a specific engine.

so... as burn_your_money said ;)
