Description

Die Erfindung bezieht sieh auf ein strömungsgünstiges Regelorgan, besonders für die Luft .von Vergasern, mit einem in die Leitung hineinbewegten Regelglied, das in jeder Stellung mit der Leitung einen strömungsgünstigen Querschnitt ergibt. Die Erfindung besteht darin, daß das Regelglied als in die Leitung hineingedrehte Kurvenscheibe ausgebildet ist.The invention relates to a flow-favorable control element, especially for the air of carburetors, with a control element moved into the line, which results in a flow-favorable cross-section in every position with the line. The invention consists in the fact that the control element is rotated into the line Cam is formed.

Gegenüber der bekannten Bauart hat die Bauart gemäß der Erfindung den Vorteil, daß das strömungsgünstige Regelglied bei voller Öffnung. vollständig aus der Leitung herausbewegt und somit ein voller Durchströmquerschnitt freigegeben ist.-Besonders einfach wird das . .Kurvenscheibenregelglied -bei viereckigem Durchströmquerschnitt.. Etwa von dem Regelglied nicht geschlossene Wandungsstücke können von einem federnd gelagerten, am Regelglied gleitenden Stück abgedeckt sein. Dabei kann das Abdeckstück entweder aus einem federnd gelagerten Gleitschieber oder aus einer B1attfederzunge bestehen.Compared to the known type, the type according to the invention the advantage that the flow-favorable control element at full opening. Completely moved out of the line and thus released a full flow cross-section is.-It will be particularly easy. .Cam control element - with a square flow cross-section .. Wall pieces, for example, which are not closed by the regulating element can be resiliently provided by a stored, sliding on the control member be covered. The cover piece either from a spring-loaded slide valve or from a leaf spring tongue exist.

Die Ahl>. i bis 3 zeigen ein Ausführungsbeispiel des Erfindungsgegenstandes mit einem Kurvenscheibenregelglied. Die Abb. i und 2 stellen in Längsschnitten den Lufteinlaßteil des Vergasers mit dein Regelglied dar', und zwar Abb. i in geschlossener und Abb. 2 in offener Stellung des Regelgliedes; Abb. 3 ist ein - Schnitt nach Linie 111-11I der Abb. 2.The Ahl>. i to 3 show an exemplary embodiment of the subject matter of the invention with a cam control element. Fig. I and 2 represent in longitudinal sections the Air inlet part of the carburetor with your control element dar ', namely Fig. I in closed and Fig. 2 in the open position of the control member; Fig. 3 is a - section along the line 111-11I of Fig. 2.

Das Lufteinlaßgehäuse i hat ein Luftfilter 2. Im engsten Teil des Gehäuses ist das Kurvenschei.benregelglied 3 angeordnet. Es hat eine Ausnehmung 4, die so gestaltet ist, daß sie in nahezu jeder Stellung zusammen mit der Leitungswand erfindungsgemäß einen strömungsgünstigen Querschnitt ergibt. Die Grundkurve ,5 der Scheit>-- 3 ist der :Motorkennung angepaßt. Damit Luftwirbelbildungen in Toträumen, die bei gewissen Stellungen vorkommen, vermieden werden, ,sind erfindungsgemäß federnde Abdeckstücke angeordnet, die gemäß. Abb: i als. Gleitschieber 6 und gemäß Abb. 2 als Blattfederzunge ausgebildet sein können. Damit auch das Luftfilter 2 der nach einer parabelförmigen Widerstandskurve einlaufenden Strömung überall gleichen Widerstand entgegensetzt, ist seine Filterwirkung ebenfalls nach einer Parabel gestaltet, so daß sieh die Filterschicht nach der Mitte :hin entsprechend verstärkt.The air inlet housing i has an air filter 2. In the narrowest part of the Housing the Kurvenschei.benregelglied 3 is arranged. It has a recess 4, which is designed so that it can be in almost any position together with the pipe wall according to the invention results in a flow-favorable cross-section. The base curve, 5 the Scheit> - 3 is adapted to the: engine identification. So that air vortices form in dead spaces, which occur in certain positions, are avoided, are according to the invention resilient Cover pieces arranged according to. Fig: i as. Slide 6 and according to Fig. 2 can be designed as a leaf spring tongue. So that the air filter 2 of the after a parabolic resistance curve flowing in, the same resistance everywhere on the other hand, its filter effect is also designed according to a parabola, see above that see the filter layer towards the middle: accordingly reinforced.

Durch die parabolische Verteilung des Durchftußwider,stan:des des Filters wird erreicht, daß die StrömungsgeschwiMigkeit des Mediums an den Leitungswandungen nicht noch mehr gegenüber der Mitte herabgesetzt, sondern vielmehr über den ganzen Querschnitt vergleichmäßigt wird, so daß unmittelbar hinter dem Filter nahezu überall dieselbe Geschwindigkeit herrscht.Due to the parabolic distribution of the flow resistance, stan: des des Filter is achieved that the flow velocity of the medium on the pipe walls not further reduced in relation to the middle, but rather over the whole Cross-section is evened out, so that almost everywhere immediately behind the filter the same speed prevails.
