Description

Kraftstoff-Einspritzpumpe Die Ertiudung bezieht sich auf eine Kraftstoff-1?insl>ritzpumpe für Brennkraftmaschinen mit V-förmig angeordneten Pumpenzylindern.Fuel injection pump The assessment relates to a fuel injection pump for internal combustion engines with V-shaped pump cylinders.

Gemäß der Erfindung ist bei einer solchen Pumpe <las Pumpengehäuse nach dem Winkelraum zwischen den Zylindern hin offen, beispielsweise für den 1?in- und :\usbau einzelner Trieb- und Regelteile, und der Winkelraum durch einen leichtabnehmbaren Deckel verschlossen. Die erfindungsgemäße Pumpe hat den Vorteil, daß alle der Einstellung dienenden Teile leicht zugänglich und durch einen einzigen Deckel gegen Verschmutzung und störende äußere 1?inftiisse während des Betriebes geschützt sind. .\ußerdem führt die vorgeschlagene Ausnutzung des Winkelraumes zu einem glatten und geschlossenen Pumpenaggregat, bei dessen Einbau es keiner besonderen Rücksichtnahme auf benachbarte Maschinenteile bedarf, die eventuell die Wartung der Pumpe erschweren könnten. Es ist eine Kraftstoff-Einspritzpumpe mit V-förmig angeordneten Pumpenzylindern bekannt, bei der allerdings das Pumpengehäuse zum Winkelraum bis auf die DUrchtrittsöffnungen für einen verschiebbaren Vorpumphebel geschlossen und der Winkelraum durch einen nicht leicht abnehmbar gestalteten Deckel verschlossen ist.According to the invention, the pump housing is used in such a pump open towards the angular space between the cylinders, e.g. for the 1? in and: \ expansion of individual drive and control parts, and the angular space with an easily removable one Cover closed. The pump according to the invention has the advantage that all of the adjustment Serving parts easily accessible and protected from contamination by a single cover and disturbing external influences are protected during operation. . \ udder the proposed use of the angular space leads to a smooth and closed one Pump set, during the installation of which there is no special consideration for neighboring Requires machine parts that could possibly complicate the maintenance of the pump. It a fuel injection pump with V-shaped arranged pump cylinders is known, in which, however, the pump housing to the angular space except for the penetration openings closed for a displaceable priming lever and the angular space by a not easily removable designed lid is closed.

In weiterer Ausgestaltung der Erfindung sind im Winkel zwilschen den Pumpenreihen einzelne, jeweils zwei sich gegenüberliegenden Pumpenelementen zugeordnete Hebel gelagert, die zum Vorpumpen von Hand dienen und .nach Abnahme des Deckels durch einen Aufsteckhebel verlängert werden können. In ihrer Mittelstellung sind ,diese Hebel durch am Deckel befestigte Federn gehalten. In weiterer Durchbildung der vorgeschriebenen besonderen Ausführungsform der erfindungsgemäßen Pumpen dienen die Vorpumphebel in ihrer Mittelstellung den beiden ihnen jeweils zugeordneten Pumpenelementen als Stößelführung. Die Stößel sind damit während des Betriebes gegen Verdrehen gesichert.In a further embodiment of the invention, the angle between the Individual rows of pumps, each assigned to two opposing pump elements Mounted levers, which are used for pre-pumping by hand and after removing the cover can be extended by a slip-on lever. Are in their middle position , these levers held by springs attached to the cover. In further Implementation of the prescribed particular embodiment of the invention Pumps, the pre-pump levers serve both of them in their middle position assigned pump elements as a tappet guide. The tappets are thus during the Secured against twisting during operation.

Die Rückführung der Pumpenhebel nach Gebrauch in ihre Mittelstellung kann entweder dadurch bewirkt werden, daß man sie so ausbildet, daß ihr Schwerpunkt unterhalb der Schwenkachse liegt, oder durch Anordnung einer oder mehrerer, sämtliche Vorpumphebel durchdringender oder verbindender, eiaiwitig im Pumpengehäuse eingespannter oder zweiseitig im Gehäuse gelagerter Biegungsfedern. Es können im letzteren Falle entweder durchgehende Biegungsfedern,beispielsweise Drähte, oder auch jeweils von Hebel zu Hebel reichende, eventuell versetzt gegeneinander verlaufende Einzelfedern vorgesehen werden.Returning the pump levers to their central position after use can either be brought about by training them so that their center of gravity lies below the pivot axis, or by arranging one or more, all Pre-pump lever penetrating or connecting, egg-like clamped in the pump housing or bending springs mounted on two sides in the housing. It can in the latter case either continuous bending springs, for example wires, or each of Single springs reaching lever to lever, possibly offset against each other are provided.

In der Zeichnung ist eine erfindungsgemäße Kraftstoff-Einspritzpumpe beispielsweise im Schnitt dargestellt.In the drawing is a fuel injection pump according to the invention for example shown in section.

Die Abbildung stellt einen Schnitt durch zwei einander gegenüberliegende Pumpenelemente dar. Diese beiden, im wesentlichen jeweils aus einem Stößel 1 bzw. 2 und einem durch eine Feder 3, 4 belasteten 5, 6 bestehenden Pumpenelemente erhalten ihre Kraftimpulse durch den Nocken 7. Zu dem von den beiden Pumpenelementen gebildeten Winkelraum 8 hin ist das Pumpengehäuse offen und erlaubt sowohl einen leichten Ausbau der Triebteile als auch zu diesen hin eine ungehinderte Kraftübertragung von den im Winkelraum untergebrachten Regel- und Kontrollorganen. Die Regelorgane bestehen aus deal beiden, parallel zu den Pumpenreihen sich bewegenden Stangen 9 und io, die mittels besonderer, in Längsnuten der Pumpenkolbenfüße eingreifenden Zapfen i i und 12 die Pümpenkolben zwecks Änderung der geförderten Kraftstoffmenge verdrehen. Zwischen den Regelgliedern 9 und io ist ein um die Welle 13 schwenkbarer Hebel 14 angeordnet, der in seiner Mittelstellung durch eine am Deckel 17 befestigte Feder 18 gehalten und in Längsnuten 15, 16 der beiden Stößel i und 2 eingreift und letztere damit während des Betriebes gegen Verdrehen sichert. Nach Entfernung des Deckels 17 kann dieser Hebel 14 bei stillstehender Maschine nach Aufstecken eines gestrichelt gezeichneten Verlängerungsstückes i9 zum Vorpumpen des einen oder anderen der beiden Pumpenelemente benutzt werden. Zur Rückführung des Hebels 14 nachGebrauch in seine Mittelstellung sind zwei ihn sowie alle anderen Hebel durchdringende, beiderseits Bim Pumpengehäuse gelagerte Stahldrähte 20, 21 vorgesehen. Nach Entfernen des Aufsteckhebels i9 stellt sich der Hebel 14 unter der Einwirkung dieser Stahldrähte 20, 21 stets in seine Mittelstellung ein und wird beim Auflegen des Deckels 17 jeweils mit Sicherheit von der Feder 18 umfaßt.The figure represents a section through two opposite one another These two, essentially each consisting of a tappet 1 or 2 and a 5, 6 existing pump elements loaded by a spring 3, 4 their force pulses through the cam 7. To that formed by the two pump elements Angular space 8 towards the pump housing is open and allows both easy removal the drive parts as well as to these an unimpeded power transmission from the Regulatory and control organs housed in the corner room. The regulatory bodies exist from the two rods 9 and io moving parallel to the rows of pumps, the pins that engage in longitudinal grooves in the pump piston feet i i and 12 turn the pump piston to change the amount of fuel delivered. A lever 14 pivotable about the shaft 13 is located between the regulating members 9 and io arranged, which is in its central position by a spring attached to the cover 17 18 held and engages in longitudinal grooves 15, 16 of the two plungers i and 2 and the latter so that it prevents twisting during operation. After removing the cover 17, this lever 14 can be shown in dashed lines after the machine is at a standstill Drawn extension piece i9 for pre-pumping one or the other of the two Pump elements are used. To return the lever 14 to its Middle position are two him and all other levers penetrating, on both sides Steel wires 20, 21 mounted in the pump housing are provided. After removing the slip-on lever i9 the lever 14 is always positioned under the action of these steel wires 20, 21 in its central position and is when the lid 17 is placed on each with security encompassed by the spring 18.
