摘要： This invention relates to a fully modulatable centrifugal pump capable of handling a fluid containing solid contaminant particles and minimizing the temperature rise of the pumped fluid. The pump is of the type that includes an impeller to propel the fluid through a radial outlet to a diffuser which includes a plurality of diffuser passages. The improvement is comprised of the following cooperative combination which includes rotatably mounted valve elements passing, in part, through the diffuser and across the diffuser passages. Each of the valve elements have a port therethrough to variably selectively allow fluid passage therethrough upon rotation of the valve element. A driving arrangement is coupled to each of the valve elements to thereby affect a yieldable rotation of the valve elements in one direction to progressively reduce the opening of the valve element port to the diffuser passage. The aforementioned driving arrangement is also drivingly coupled to the valve elements to provide a direct mechanical coupling to the valve element to thereby affect a nonyieldable rotation of the valve element in an opposite direction to increase the opening of the valve port to the diffuser passage, to thereby ensure that contaminant particles that lodge between a portion of said valve port and the diffuser passage and interrupt movement of one or more valve element port closings do not prevent the remaining valve port elements from closing. During the opposite rotation of the valve elements there is a direct mechanical drive that ensures the opening of the valve port to thereby release the contaminant particle and allow passage of the particle from the valve element and the diffuser.

摘要： A boost pump incorporates a low-flow impeller pump for charging the inlet of a gas producer fuel pump and a high-flow impeller pump for charging the inlet of an augmentor fuel pump. The low-flow pump is connected to a drive shaft so as to be continuously driven thereby. The drive shaft may be placed in driving connection with the high-flow pump through the medium of a friction clutch which is engageable by the application of a fluid pressure. Disengagement of the high-flow impeller, when augmentation is not required, significantly contributes to an increase in pump efficiency and a reduction in heating of the fluid being pumped.

摘要： The use of a single main centrifugal fuel pump for supplying fuel to an aircraft gas turbine engine has advantages over other known systems, however a problem has existed in that the centrifugal pump, when driven in a fixed ratio to the engine speed, cannot deliver fuel at adequate pressure under engine starting conditions. The disclosed fuel supply system using a main centrifugal pump overcomes this shortcoming by having a turbine-driven start pump added to the fuel supply with both the turbine and the start pump receiving fuel pumped by the main centrifugal pump and the turbine utiliziing the high flow, low pressure fuel to drive the start pump which incresases the pressure of the fuel to a value adequate for engine starting. The start pump delivers fuel until such time as the main centrifugal fuel pump has reached a speed to provide the fuel to the engine at the required pressure, at which time the turbine is no longer driven and the output of the start pump goes to zero.

摘要： A lubrication scavenge system for an engine bearing compartment or the like utilizing a gear pump with two or more independent inlets with separate flow paths through the pump. The inlets and flow paths are maintained separate from each other by the use of inlet and discharge seal arcs to avoid any fluid communication therebetween. The pump can operate to pump different fluids through each inlet with the fluid being either a gas or liquid or a mixture of both and with the pump continuing its pumping action when there is an instantaneous interchange in the fluid being pumped at each inlet as can occur when the engine bearing compartment is subjected to varying positive and negative gravity forces.

摘要： A regenerative pump which has a controlled output by having movable lateral channel arcuate slots (36, 38) in channel plates (26) which are on opposite sides of a bladed rotor (18). The channel plates (26) are mounted for sliding movement to reduce the effective vortex channel length in a range from about 325.degree. to about 40.degree.. This will result in a proportional reduction of pump pressure rise and input power requirements. The position of the channel plates may be varied by a servo system that responds to a desired system output performance such as pressure rise or flow delivery rate.
