Abstract (en)
A fluid pump (18) comprising a housing (30) receiving a camshaft (36) which is rotatable within rotational guiding means (38a, 38b), the camshaft cooperating with a pumping plunger of the fluid pump to actuate the pumping plunger to reciprocally move in order to pressurize fluid within a pump chamber, the camshaft (36) being exposed to a fluid to lubricate the camshaft, in use, characterized in that the camshaft (36) is provided with an integral fluid damper (42) comprising a bellows device (42) configured to damp hydraulic waves propagating in the return and inlet lines in the fluid lubricating the camshaft (36) and flowing through the rotational guiding means (38a, 38b).
