Title: Oil-lubricating system for the bearing arrangement of a shaft journal in a rotating shaft
Inventor: FUEHRER GERD
IPC: F16H57/04
Filed: 1989-03-06
Abstract: Oil-lubricating system for the bearing arrangement of a shaft journal (31) in a rotating shaft (2), in particular a journal bearing (1) for a main shaft (3) in a gearing, in which system the lubricating oil is supplied, as a priority, radially inwards on one side (11) of the journal bearing (1) and is discharged radially outwards on the other side (12) via an annular duct (8) resulting between the two shafts. Arranged in the annular duct, which acts as outlet duct (8) of the lubricating oil, is a rubber-elastic seal (4) which, during operation, is opened by the centrifugal force or by the pressure of the lubricating oil and closes the outlet duct (8) only when the gearing is at a standstill. The rubber-elastic seal (4) can be fixed via an element (44) in or on the gearing input shaft (2), especially if the sealing lip (41) is to be opened by centrifugal force. It can, however, also be fixed to the gearing main shaft (3) if, as a priority, the sealing lip is to be opened by the pressure of the lubricating and cooling oil issuing from the journal bearing (1). <IMAGE>

Patent DE-4034473-A1 (DE)
Inventor: MAYER RUDI
IPC: F02D41/18
Filed: 1990-10-30
Abstract: The proposal is for a fuel metering system for an internal combustion engine with a throttle flap in the air intake pipe, a controllable by-pass on the throttle flap and a signal processing unit to form a fuel metering signal based at least on the values of the throttle flap angle, the control signal of the by-pass adjuster and the rotation speed, whereby the fuel metering signal is found via the formation of virtual total signals concerning the air through-flow area or throttle flap angle and subsequently rotation-speed-dependent characteristic output. In an alternative solution, the fuel metering signal is formed from the sum of a component dependent on the rotation speed and throttle flap angle and a by-pass dependent component, whereby the latter is corrected dependently on the rotation speed and a signal derived from the throttle flap angle.
