    Abstract: An engine fuel control system is provided. The system includes a fuel metering valve operable to control the flow of fuel between a supply line and a delivery line which delivers fuel to burners of the engine. The system further includes a fixed displacement main pump which receives fuel from a low pressure source and delivers the fuel at a first high pressure to the supply line. The system further includes a variable displacement augmenter pump which receives fuel from the low pressure source and delivers the fuel at a second high pressure to one or more fuel-pressure operated auxiliary engine devices. The augmenter pump has a servo-controller to vary its pump flow rate such that the fuel delivery flow rate of the augmenter pump is varied to compensate for fuel flow demands imposed by the auxiliary engine devices. The system further includes an augmentation valve which is actuated at selected engine operating conditions to open a flow path through the augmentation valve which diverts fuel delivered by the augmenter pump away from the auxiliary engine devices to the supply line to augment the fuel delivered thereto by the main pump. The augmentation valve is actuated at other engine operating conditions to shut the flow path. The system further includes a pressure drop control valve which senses a pressure differential between the second high pressure and a reference pressure. The pressure drop control valve is arranged to control the servo-controller such that the pump flow rate of the augmenter pump is varied to maintain the pressure differential at a predetermined level. The pressure drop control valve is configured to spill, at the other engine operating conditions, a portion of the fuel delivered by the augmenter pump away from the auxiliary engine devices to the supply line to augment the fuel delivered thereto by the main pump. The system further includes an electrically operated control valve which is operable to actuate the augmentation valve.

    Abstract: The invention relates to a mortar mixing pump (10) comprising a motor driven conveying screw (14) which guides material which is to be mixed into a mixing chamber (18) which is provided with a lining (52) made of rubber and plastic, said material being arranged at least in an essentially coaxial manner in relation to the conveying screw (14). The liquid can be fed through one or several liquid injection nozzles. A mixing element (36), which rotates with the conveying screw (14), is received in the mixing chamber (18) in order to mix the material conveyed into the mixing chamber (18) with liquid. The end of the mixing chamber which is arranged at a distance from the conveying screw (14) is defined by a specific pump flange (20) for connection to the pump (22). In order to improve the entire operating manner, especially to reduce each deposition of material, and to simplify purification, the conveying screw (14) is arranged in a funnel (12) which is used to fill the material which is to be mixed. The mixing chamber (18) is configured as a component which is separate from the funnel (12) and the pump flange (20) and which is connected to the funnel (12). The lining (52) of the mixing chamber (18) is in direct contact with the funnel (12) and with the surface of the pump flange (20), and a plurality of liquid injection nozzles (6) are received in a nozzle carrier (60) which is arranged in a recess of the lining (52) in an at least approximately flush manner with the inner surface of the lining (52) and which can be detachably fixed to the outside of the mixing chamber (18) by means of accessible fixing means.

    Abstract: A demand system is disclosed for controlling the output airflow from a pneumatic source in response to changes in airflow demand. The source includes a pressure sensitive bypass mechanism in fluid communication with a discharge manifold to divert unwanted airflow and a linear electronic limiter with a limiter signal input to control the pneumatic source and proportionally adjust output airflow into the discharge manifold. The demand system includes an airflow detector operative to produce a linear output signal proportional to the airflow through the bypass mechanism and a controller. The controller includes an input connected to the airflow detector and an output connected to the electronic limiter input and operative, as the airflow detector senses airflow through the bypass mechanism, to produce a linear output signal representative of the airflow to the limiter for altering the pneumatic source output.
