Abstract (en)
[origin: EP3269979A1] A pump comprises: - a plurality of pistons (5) each of which is slidable inside a cylinder so as to vary volume of a corresponding chamber (6), - a plurality of suction valves (16), each of which is associated with a chamber (6) and is operable to allow a liquid to enter the chamber (6), the suction valves (16) being arranged in a first sequence, - a plurality of delivery valves (17), each of which is associated with a chamber (6) and is operable to allow said liquid to exit from the chamber (6), the delivery valves (17) being arranged in a second sequence, - an adjusting valve (25) for adjusting pressure of the liquid exiting from the pump (1). The adjusting valve (25) is interposed between two consecutive valves of a sequence chosen from said first sequence and said second sequence.
