<p>The invention relates to an arrangement in a pump block (4). The pump block (4) includes a plurality of pump valves (3) each connected to a piston (20) in a piston pump (21). The pump block (4) also includes an inlet pipe (1) which is common to all of the pump valves (3). The inlet pipe has a connection (2) to each pump valve (3). One connection (2) between the inlet pipe (1) and the pump block (4) is fixed (9) and includes a flange (10) fixedly screwed in the pump block (4), the remaining connections (2) are movable (16) in the longitudinal direction of the inlet pipe (1). The movable connections (16) each include a flange (17) with over-dimensioned boltholes (18) in which a spacer (19) is placed.</p> |
