Abstract
The invention relates to an arrangement in a pump block. The pump block includes a plurality of pump valves each connected to a piston in a piston pump. The pump block also includes an inlet pipe which is common to all of the pump valves. The inlet pipe has a connection to each pump valve. One connection between the inlet pipe and the pump block is fixed and includes a flange fixedly screwed in the pump block, the remaining connections are movable in the longitudinal direction of the inlet pipe. The movable connections each include a flange with over-dimensioned boltholes in which a spacer is placed.
