Abstract: A rotating drum-shaped cylinder block with pistons longitudinally displaceable in the cylinder bores is mounted in the housing of a reciprocating-piston pump of inclined-disc construction. The cylinder block is fitted on the free end of a rotating driving shaft which, in a median zone along its length, is mounted on two roller bearings in a bearing box which is completely sealed off from the machine housing. The pistons are supported in piston shoes on a stationary inclined disc the inclined position of which can be adjusted in the machine housing. For the purpose of sealing off the machine housing from the bearing box, there are slide-ring sealing means composed of a rotating ring secured to the driving shaft and of a stationary ring in the machine housing.

Abstract: In the case of internal combustion engines which are fuelled by a liquefied gas (LPG), in particular spark-ignition gas engines, the engines are often incorrectly adjusted since the composition of the liquefied gas is not standardised and the mixing ratio of the main constituents propane and butane may vary greatly. The calorific value of liquefied gases can therefore fluctuate considerably and in the case of internal combustion engines fuelled by this means performance settings may be incorrect, leading to cut-out of the combustion engines. The compensation valve (1) proposed by the present invention varies the quantity of gas fed to the combustion engine as a function of control variables, in particular the liquefied gas pressure and, where appropriate, the liquefied gas temperature. This ensures that the combustion engine (30) is adjusted to a performance setting suited to the composition of the gas. <IMAGE>

The process for operating the fluidised bed reactor is distinguished in that sequential opening of the gas introduction openings (5) on the segment-like fittings results in cyclic gas introduction into the reactor.
