Die Aufgabe wird dadurch gelöst, daß der Pumpeneingang an den Gehäuseraum angeschlossen ist, daß an dem in den Gehäuseraum ragenden Abschnitt der Antriebswelle ein Schleuderring angebracht ist und daß ein Ansaugkanal vom Gehäuseraum zum Einlaßventil führt. Dadurch wird mit einfachen Mitteln und geringem baulichen Aufwand eine Aufladung der Pumpe erreicht. Der durch den Schleuderring erzeugte Druck sorgt stets für eine optimale Füllung des Arbeitsraumes des Kolbens. The task is solved in that the pump input on the housing space is connected to that in the Section of the drive shaft protruding into the housing Sling ring is attached and that an intake duct from Housing space leads to the inlet valve. This will help with simple means and little construction effort Pump charging reached. The one through the sling ring generated pressure always ensures an optimal filling of the Working area of the piston.
Bei einer bevorzugten Ausführung der Erfindung ist vorgesehen, daß der Schleuderring radial nach außen verlaufende Rippen oder Schaufelprofile aufweist. Durch eine solche Maßnahme kann der Aufladungseffekt des Schleuderringes noch gesteigert werden.In a preferred embodiment of the invention provided that the slinger ring radially outwards has running ribs or blade profiles.

Eine weitere Verbesserung der Aufladung wird dadurch erreicht, daß der Exzenter stirnseitig mit einer Axialbohrung versehen ist, an die sich radial verlaufende Austrittskanäle anschließen, die in umittelbarer Nähe des Schleuderringes in den Gehäuseraum mündet.This will further improve charging achieved that the eccentric with a Axial bore is provided to the radially extending Connect outlet channels that are in the immediate vicinity of the Sling ring opens into the housing space.
Verbessert wird der Wirkungsgrad der Radialkolbenpumpe dadurch, daß das Einlaßventil ein Ventilschließglied aufweist, dessen Verschlußteil sich auf der dem Arbeitsraum zugewandten Seite des Ventilsitzes befindet, während die Ventilfeder auf der gegenüberliegenden Seite des Ventilsitzes vorgesehen ist.The efficiency of the radial piston pump is improved in that the inlet valve is a valve closing member has, the closure part on the Side of the valve seat facing the work area, while the valve spring is on the opposite side of the valve seat is provided.

Weitere erfindungswesentliche Merkmale sowie die Funktion der Radialkolbenpumpe ergeben sich aus der nachstehenden Beschreibung der Erfindung anhand der Zeichnung eines bevorzugten Ausführungsbeispiels.Further features essential to the invention and the function the radial piston pump result from the following Description of the invention with reference to the drawing of a preferred embodiment.
Die dargestellte Radialkolbenpumpe besitzt einen Zylinderblock 1 mit einer gestuften Axialbohrung 2, in die ein Gehäuseabschnitt 3 eines nicht dargestellten Antriebsmotors gedichtet eingepaßt ist. Die Axialbohrung 2 ist als Sackbohrung ausgeführt und bildet nach Einsetzen des Antriebsmotors in den Zylinderblock 1 einen Gehäuseraum 8. In diesem Gehäuseraum 8 ragt axial die im Gehäuseabschnitt 3 des Antriebsmotors durch die Dichtung 9 abgedichtete Antriebswelle 4 sowie der an ihrer Stirnseite angeformte Exzenter 5. Senkrecht zur Achse der Antriebswelle 4 ragen die radial inneren Endabschnitte der Kolben 6, 7 in den Gehäuseraum 8, die sich auf dem Außenring 10 eines Wälzlagers abstützen, das auf dem Exzenter 5 angebracht ist. Um den Außenring 10 führt berührungsfrei ein Koppelring 11 , dessen axiale Fortsätze in Ringnuten der inneren Endabschnitte der Kolben 6, 7 greifen. Konzentrisch zur Axialbohrung 2 ist am Boden dieser Sackbohrung die Eingangsbohrung 13, die in Verbindung mit einem Behälter steht, angebracht. Radial nach außen versetzt zweigen die Ansaugkanäle 14 a, 14 b aus dem Gehäuseraum 8 ab. Diese verlaufen mit einem Winkel von etwa 15° zur Axialbohrung 2 radial nach außen zu den Einlaßventilen 15 a, 15 b, welche als Rückschlag ventile ausgebildet sind. Die Bohrungen, in welchen die Einlaßventile 15 a, 15 b verschraubt sind, werden durch Stopfen 17 a, 17 b, die mit dem Zylinderblock 1 verstemmt sind, druckdicht verschlossen.The radial piston pump shown has a cylinder block 1 with a stepped axial bore 2 , in which a housing section 3 of a drive motor, not shown, is fitted in a sealed manner. The axial bore 2 is designed as a blind bore and forms a housing space 8 after the drive motor has been inserted into the cylinder block 1 . In this housing chamber 8 axially protrudes beyond the sealed portion in the housing 3 of the drive motor through the seal 9 and the drive shaft 4 is integrally formed on its end face cam. 5 Perpendicular to the axis of the drive shaft 4, the radially inner end portions of the pistons 6 , 7 protrude into the housing space 8 , which are supported on the outer ring 10 of a roller bearing which is attached to the eccentric 5 . A coupling ring 11 leads around the outer ring 10 without contact, the axial extensions of which engage in ring grooves of the inner end sections of the pistons 6 , 7 . Concentric to the axial bore 2 , the input bore 13 , which is connected to a container, is attached to the bottom of this blind bore. The intake channels 14 a , 14 b branch off radially outward from the housing space 8 . These extend at an angle of about 15 ° to the axial bore 2 radially outward to the inlet valves 15 a , 15 b , which are designed as check valves. The holes in which the inlet valves 15 a , 15 b are screwed are closed by plugs 17 a , 17 b , which are caulked to the cylinder block 1 , in a pressure-tight manner.
Die Einlaßventile 15 a, 15 b zeichnen sich dadurch aus, daß das Einlaßventil 15 a, 15 b ein Ventilschließglied 24 aufweist, dessen Verschlußteil 25 sich auf der dem Arbeitsraum 16 a, 16 b zugewandten Seite des Ventilsitzes 26 befindet, während die Ventilfeder 27 auf der gegenüber liegenden Seite des Ventilsitzes 26 vorgesehen ist. Die Rückschlagventile 15 a, 15 b; 18 a, 18 b werden als vorge fertigte Einheit in den Zylinderblock 1 eingeschraubt. The inlet valves 15 a , 15 b are characterized in that the inlet valve 15 a , 15 b has a valve closing member 24 , the closure part 25 of which is located on the side of the valve seat 26 facing the working space 16 a , 16 b , while the valve spring 27 is on the opposite side of the valve seat 26 is provided. The check valves 15 a , 15 b ; 18 a , 18 b are screwed into the cylinder block 1 as a pre-manufactured unit.
Durch einen kurzen Kanal sind die Einlaßventile 15 a, 15 b mit dem jeweiligen Arbeitsaum 16 a, 16 b verbunden, an den sich jeweils radial nach außen gerichtet das zugehörige Auslaßventil 18 a, 18 b anschließt, welches jeweils mit einem eigenen (nicht dargestellten) Pumpenausgang verbunden ist.Through a short channel, the inlet valves 15 a , 15 b are connected to the respective working area 16 a , 16 b , to which the associated outlet valve 18 a , 18 b connects, each directed radially outward, each with its own (not shown) Pump outlet is connected.
Zwischen der Dichtung 9 und dem Wellenabsatz zum Exzenter 5 ist auf der Antriebswelle 4 der Schleuderring 12 vorgesehen, der mit der Antriebswelle 4 fest verbunden ist. Bei sich drehender Antriebswelle 4 erzeugt der Schleuderring 12 Rotationskräfte auf die sich im Gehäuseraum 8 befindliche Flüssigkeit, wodurch sich in den Ansaugkanälen 14 a, 14 b ein Staudruck aufbaut. Diese Aufladung der Radialkolbenpumpe wird noch durch die an der Stirnseite des Exzenters 5 angebrachte Axialbohrung 20 mit den zugehörigen radialen Austrittskanälen 21, die zusätzlich zum Schleuderring 12 eine radial nach außen gerichtete Strömungskomponente erzeugen, erhöht.Between the gasket 9 and the shaft shoulder to the eccentric 5, the slinger 12 is provided on the drive shaft 4 which is fixedly connected to the drive shaft. 4 When the drive shaft 4 rotates, the centrifugal ring 12 generates rotational forces on the liquid located in the housing space 8 , as a result of which a dynamic pressure builds up in the intake ducts 14 a , 14 b . This charging of the radial piston pump is further increased by the axial bore 20 provided on the end face of the eccentric 5 with the associated radial outlet channels 21 which, in addition to the centrifugal ring 12 , produce a radially outward flow component.
Der Schleuderring 12 kann wie dargestellt eine ebene Stirnseite 22 und eine axial in den Gehäuseraum 8 umgestülpte Krempe 23 aufweisen. Besonders günstig erscheint die Ausbildung der Stirnfläche 22 als strömungserzeugendes Profil, beispielsweise mit radial nach außen verlaufenden Rippen oder als Schaufelprofil.As shown, the slinger ring 12 can have a flat end face 22 and a brim 23 which is turned axially into the housing space 8 . The design of the end face 22 as a flow-generating profile appears particularly favorable, for example with radially outwardly extending ribs or as a blade profile.
Die Radialkolbenpumpe arbeitet in an sich bekannter Weise. Sie saugt, beispielsweise aus einem drucklosen Behälter, das zu fördernde Fluid über die Eingangsbohrung 13 in den Gehäuseraum 8, wobei der Hauptstrom über die Axialbohrung 20 und die Austrittskanäle 21 führt. Die durch den Schleuderring 12 erzeugten Strömungskräfte erzeugen einen Aufladedruck in den Ansaugkanälen 14 a, 14 b, der für eine stets optimale Füllung der Arbeitsräume 16 a, 16 b sorgt. Nach einem durch den Exzenter bewirkten Arbeitshub radial nach außen, sorgt der Koppelring 11 für den radial nach innen gerichteten Saughub. The radial piston pump works in a manner known per se. It sucks, for example from a non-pressurized container, the fluid to be conveyed via the inlet bore 13 into the housing space 8 , the main flow passing through the axial bore 20 and the outlet channels 21 . The flow forces generated by the centrifugal ring 12 generate a supercharging pressure in the intake ducts 14 a , 14 b , which ensures that the working spaces 16 a , 16 b are always optimally filled. After a working stroke caused by the eccentric radially outward, the coupling ring 11 ensures the radially inward suction stroke.
