Abstract: The invention relates to a pressure regulating and cut-off valve for fuel pumps which includes a setting piston and a combination of two pistons for regulating the pressure outlet between predetermined pressure levels. A pair of springs are provided for resisting movement of the setting piston which are arranged in parallel and have different rectilinear spring rates. The providing of this pair of springs results in space saving, permits a wider adjustment range and is less affected by manufacturing tolerance deviations.

Abstract: The invention relates to a rotary seal unit of the type used for oil pumps and the like. A plastic backing ring having a tapered surface is nested in a conical recess of a face ring. The taper angle of the tapered surface of the backing ring is larger than the taper angle of the conical recess. A resilient sealing ring is spring biased to force the plastic backing ring into contact with the face ring which in turn is biased into sealing engagement with a fixed sealing surface of a stationary bearing block.

Abstract: The invention relates to pump control apparatus of the type used for supplying fuel oil at a constant pressure to the nozzle of an oil burner unit. The control apparatus comprises a valve assembly for performing pressure regulating, cut-off and venting function. The venting function is performed when the pump is started by a venting valve interposed between the supply and return pipes. The venting valve is controlled so as to close before the predetermined operating pressure is reached at which time a cutoff valve opens to allow pressurized fluid to be delivered by the valve assembly.

Abstract: The invention relates to an oil pump unit for oil burners which includes a known assembly of a geared pump, a sump at a lower level, and a pressure regulator valve. Air vent means are provided which includes apparatus for feeding back to the pump pressurized liquid from the pressure regulator. The pump proper has novel passage means for receiving the fed back pressurized liquid to the pumping chambers to effect a venting of pressurized air from the chambers.

Abstract: The invention relates to a pump of a type commonly used for oil burners having kidney shaped inlet and exhaust passages formed in a wall adjacent the pumping elements of the pump. Based on the discovery that air pockets are formed in the suction inlet when there is an appreciable decrease in the velocity of the liquid being sucked through the inlet passage or passages, inlet passage means are provided having nondecreasing cross sections so as to maintain nondecreasing velocities of liquids flowing therein.

Abstract: A ROTARY SEAL COMPRISES A SHAFT ROTATABLY MOUNTED IN A HOLLOW HOUSING WHICH HAS A RECESSED PORTION. WITHIN THIS RECESS THERE IS A RING-SHAPED SEAT PORTION DISPOSED COAXIALLY WITH THE SHAFT. A STATIONARY BEARING SEAT MEMBER COMPRISING A SINTERED CARBON RING HAVING A FLAT BEARING SURFACE IS PRESSED AGAINST THE RING-SHAPED SEAT BY SPRING MEANS. THE SURFACE OF THE CARBON RING OPPOSITE THE FLAT BEARING SURFACE IS PREFERABLY IMPREGNATED WITH A MATERIAL SUCH AS A METAL TO AVOID POROSITY. HOWEVER THE IMPREGNATING MATERIAL DOES NOT REACH THE FLAT BEARING SURFACE. A ROTATABLE METAL SEALING RING MEMBER IS
PRESSED AGAINST THE SINTERED CARBON RING THUS PRODUCING A SEAL BETWEEN THESE MEMBERS.-
