US 5,630,698 A · Converter for providing a liquid at a measurement pressure corresponding to a rotational speed

Abstract

A converter assembly for providing a liquid in a measuring line includes a stationary housing and a component being rigidly connected to the housing. A journal is slidingly supported in the stationary housing and defines a gap disposed between the component and the journal forming a throttle. The journal has an axis of rotation, an end, at least one transverse bore formed in the journal, and a journal bore formed in the journal from the end along the axis. The housing has a groove formed therein surrounding the journal and communicating with the journal bore through the at least one transverse bore. A liquid flow path communicates with a reservoir at a primary pressure and a pressureless sump and includes the throttle, the groove, the transverse bore and the journal bore. A measuring line branching off from the path between the transverse bore and the throttle carries the liquid at a measurement pressure corresponding to a rotational speed of the journal rotating about the axis.
