The invention relates to a port plate (1) for a fluid throughput regulating device, comprising at least one fluid blocking section, and at least one flu- id conduit means (7, 9, 10, 13, 14, 15, 17, 18, 19) that fluidly connects two surface parts (2, 3) of said port plate (1). Said fluid conduit means (7, 9, 10, 13, 14, 15, 17, 18, 19) comprises at least one fluid conduit (14) that is bent in a way that there is no line-of-sight axis between the surface parts (2, 3) that are connected by the respective fluid conduit (14).
