Device for feeding fluid to pump has different degrees of alignment between openings during distribution element sleeve rotation depending on sleeve's longitudinal position

摘要

The device has a distribution element with a housing with a bore containing an axially and rotationally movable sleeve with a side opening connected to the fluid port. The housing has at least one opening into the bore connected to the input port. There are arrangements for setting the longitudinal sleeve position and turning it. Different degrees of alignment exist between openings during sleeve rotation depending on the sleeve's axial position. The device has a distribution element with a housing (4) with a bore (6) containing a longitudinally and rotationally movable sleeve (7) with a side wall opening (10) connected to the fluid port (5). The housing has at least one opening (11) into the bore connected to the input port (23). There are arrangements for setting the longitudinal sleeve position and for turning it. Different degrees of alignment exist between the openings during sleeve rotation depending on the sleeve's longitudinal position.
