Abstract: A rotary valve has a valve plug that is rotatable in a valve body about a rotational axis. Surface features of the valve plug and surface features of the valve body cooperate to provide a bearing by which the valve plug is rotatably supported with respect to the valve body. In addition, each of the valve plug and the valve body include a plurality of annular projections that encircle the plain bearing and axially overlap one another so as to form a labyrinth that surrounds the bearing. The labyrinth forms a fluid path that collects abrasive particles suspended in the fluid passing through the valve, whereby wear of the valve is reduced.

Abstract: A computer-implemented method for testing a system, the tested system being a computer program, a hardware system, or an embedded system. In the method, using a static analysis, a first part of an execution structure for the system is examined to see if the system runs corresponding execution paths without errors when the first part of the execution structure is executed. If in the static analysis error-free execution is determined for the first part of the execution structure, the system is examined using a dynamic analysis which leaves out execution paths which correspond to the first part of the execution structure.
