Description

II

Изобретение касаетс  насосостроени , ,в частности конструкции вихревых насосов сэлектроприводом, и может быть использовано при проектировании таких устройств.The invention relates to pump-building, in particular the design of vortex pumps with an electric drive, and can be used in the design of such devices.

Известен агрегат дл  подачи топлива, содержащий вихревой насос с боковым подводом топлива, ротор которого закреплен на валу электродвигател , а всасьшающа  полость выполнена в статоре в виде открытого к ротору кольцевого паза с подвод щим и нагнетательным каналами и соответствующего кольцевого паза в роторе flj .A known unit for supplying fuel contains a vortex pump with lateral fuel supply, the rotor of which is fixed to the motor shaft, and the absorbing cavity is made in the stator as an annular groove open to the rotor with supply and discharge channels and a corresponding annular groove in the rotor flj.

Цель изобретени  - уменьшение радиальных размеров агрегата.The purpose of the invention is to reduce the radial size of the unit.

Это достигаетс  тем, что нагнетательный канал выполнен радиальным и направлен к оси агрегата 3, на радиусе, меньщем , чем радиус кольцевого паза в стато ре, выполнена открыта  к ротору выточка в которую входит радиальный нагнетательный канал, в роторе выполнена ответна  открыта  к статору выточка, соединенна  с подающей стороной насоса, причем This is achieved by the fact that the discharge channel is made radial and directed to the axis of the unit 3, at a radius smaller than the radius of the annular groove in the stator, the recess is open to the rotor and the radial discharge channel is in the rotor, the recess is open to the stator, connected to the supply side of the pump, and

в торцевой поверхности статора, обращенной к ротору, на радиусе начала кольцевого паза, за концом последнего, по направлению ротора вьшолнена полость сброса , соединенна  с нагнетательным каналом .in the end surface of the stator, facing the rotor, on the radius of the beginning of the annular groove, behind the end of the latter, in the direction of the rotor, there is a discharge cavity connected to the discharge channel.

На чертеже схематически изображен агрегат дл  подачи топлива, продольный разрез.The drawing shows schematically a fuel supply unit, a longitudinal section.

Агрегат дл  подачи топлива содержит кбрпус 1 вихревого насоса с боковым подводом топлива, ротор 2, закрепленный на валу 3 электродвигател  4 с кольцевым пазом а ротора и кольцевой выточкой 5, и статор 6 с подвод щим 7 и нагнетательным 8 каналами, кольцевым пазом б, кольцевой выточкой 9 и полостью А сброса .The fuel supply unit comprises a vortex pumping unit 1 with a side fuel supply, a rotor 2 mounted on the shaft 3 of an electric motor 4 with an annular groove a rotor and an annular recess 5, and a stator 6 with a feed 7 and an 8-channel discharge, annular groove b, annular groove 9 and cavity A reset.

Агрегат дл  подачи топлива работает следующим образом.The unit for fuel supply works as follows.

Claims (4)

Топливо поступает в корпус 1 насоса, а затем через подвод щий канал 7 статора 6 - в кольцевой паз б, взаимодействует с элементами кольцевого паза а ротора 2 и поступает по нагиетательному каналу 8 в кольцевую вытсгчку 9 статора, а затем в кольцевую выточку 5 ротора на выход агрегата. Формула изобретени  1.Агрегат дл  подачи топлива, содер жащий вихревой насос с боковым подводом последнего, ротор которого закреплен на валу электродвигател , а всасывающа  полость выполнена в статоре в виде откры того к ротору кольцевого паза с подвод щим и нагнетательным каналами и соответствующего ему кольцевого паза в роторе , отличающийс  тем, что, с целью уменьшени  радиальных размеров нагнетательный канал выполнен радиальным и направлен к оси агрегата, The fuel enters the pump housing 1, and then through the inlet channel 7 of the stator 6 into the annular groove b, interacts with the elements of the annular groove of the rotor 2, and enters the stator 9 in the annular channel 8 and then into the annular recess of the rotor 5 unit output. Claim 1. The unit for fuel supply, containing a vortex pump with lateral supply of the latter, the rotor of which is fixed on the motor shaft, and the suction cavity is made in the stator in the form of an annular groove open to the rotor with supply and discharge channels and the corresponding annular groove in the rotor, characterized in that, in order to reduce the radial dimensions, the discharge channel is made radial and directed towards the axis of the unit, 2.Агрегат по п. 1, отличающийс  тем, что на радиусе, меньшем , чем радиус кольцевого паза, в статоре выполнена открыта  к ротору выточка , в которую входит радиальный нагнетательный канал. 2. The unit according to claim 1, characterized in that at a radius smaller than the radius of the annular groove, in the stator the recess, which includes the radial discharge channel, is open to the rotor. 3.Агрегат по п 2, о т л и ч а ющ и и с   тем, что в роторе выполнена ответна  открыта  к статору выточка, соединенна  с подающей стороной насоса. 3. The unit according to claim 2, which also means that the rotor is made in response to the recess open to the stator connected to the supply side of the pump. 4.Агрегат по пп. 1, 2 и 3, о т л ичающийс  тем, что в торцевой поверхности статора, обращенной к ротору , на радиусе начала кольцевого паза, за концом последнего, по направлению потока выполнена полость сброса, соединенна  с нагнетательным каналом. Источники информации, прин тые во внимшше при экспертизе: 1. Опубликованна  за вка ФРГ № 17О3784, кл. 59 в, 4, 1968.4. The unit on the PP. 1, 2 and 3, about the fact that in the end surface of the stator, facing the rotor, on the radius of the beginning of the annular groove, behind the end of the latter, in the direction of flow there is a discharge cavity connected to the discharge channel.
