(Industrial Application Field) The present invention is a multiple carburetor engine in which a carburetor is installed in each cylinder of an engine divided into two sets, and the throttle valves of each carburetor are opened and closed in synchrony. This relates to a throttle valve interlocking device for a vessel, and is mainly used to supply air-fuel mixture to a horizontal V-shaped 2F engine for small ships. (Prior art) As a system for supplying air-fuel mixture to the engine of a small boat, it is widely known that a carburetor is installed in each cylinder of the engine, and the throttle valves of each carburetor are opened and closed in synchronization by an interlocking device. It has been put into practical use.The throttle valve interlocking device of this multiple carburetor is a horizontal rank mechanism in which the throttle valve levers fixed to each throttle valve shaft are connected by a connecting rod. The throttle valves are opened and closed synchronously by rotating the throttle valve within an angular range of 90 degrees (see Japanese Patent Application Laid-Open No. 150444/1983). If a multiple carburetor is used, in which throttle valves are linked by a mechanism, if the carburetors are arranged so that the flow of intake air is directed toward the center of the engine and the intake efficiency is increased, the cylinders are divided into two sets facing each other. The two sets of carburetors installed in each set are arranged so that their throttle valve shafts extend in directions that intersect with each other.The throttle valves of one set of carburetors are individually tuned by the parallel rank mechanism as described above. However, in order to synchronize the two sets, the two sets of horizontal rank mechanisms must be interlocked with each other. The carburetor is placed toward the center of the engine to improve intake efficiency, and the throttle valves of the carburetor installed in one set of cylinders are synchronously opened and closed by a parallel rank mechanism, and two sets of parallel rank mechanisms are used. To date, no device has been provided that can synchronize the throttle valves of two sets of vaporizers and smoothly open and close them. (Problems to be solved by the invention) The technical problems to be solved by the invention are as follows. A separate carburetor is installed in each cylinder of the horizontal V-shaped engine.
In a case where intake efficiency and fuel distribution are improved by synchronized opening and closing of throttle valves of the carburetor installed in one set of cylinders, which are divided into two sets of cylinders, using a parallel rank mechanism. To provide a throttle valve interlocking device that completely synchronizes two sets of parallel rank mechanisms to prevent variations in the throttle valve opening K, especially in the low opening range (and allows smooth interlocking with a small force). (Means for Solving the Problems) In order to solve the above-mentioned technical problems, the present invention provides two sets of a plurality of carburetors whose throttle valves are synchronously opened and closed by a parallel rank mechanism. In a multiple carburetor, the throttle valves of the two sets of carburetors are arranged with their throttle valve shafts aligned in the same direction in a crossing direction, and the two sets of parallel rank mechanisms are interlocked by a crank interlocking mechanism to open and close the throttle valves of the two sets of carburetors, The crank interlocking mechanism has a crank lever fixed to one throttle valve shaft of each group, and each crank lever is connected by two links arranged on both sides of each throttle valve shaft. However, it is preferable that the two links be arranged at right angles to each throttle valve axis in the throttle valve low opening range. When opened and closed by operation, the throttle valves of the carburetor of that group open and close in synchrony with each other by a parallel crank mechanism.The rotation of the throttle valve shaft of one of the groups causes the throttle valve of the other group to open and close due to the crank interlocking mechanism. The transmission is transmitted to the shaft, and the throttle valves of the second set of carburetors are opened and closed in synchrony by the horizontal rank mechanism.The two links placed on both sides of the throttle valve shaft of the crank interlocking mechanism are connected to the crank lever. One link presses and the other link pulls to apply rotational force, without bending the throttle valve shaft (by rotating, the throttle valves of two sets of carburetors are opened and closed in synchrony. (Example) The present invention will be described in detail with reference to the drawings. The drawings show the case where the present invention is implemented in a horizontal V-shaped six-cylinder engine, and the first, third, and fifth cylinders, the second, fourth, and The sixth cylinder is one set, and the former has three horizontal carburetors 1.3.5 installed in each of the first set of cylinders, and the latter has a second set of carburetors 1.3.5.

) rotates in the direction of the arrow 10,000 times by operating the accelerator to increase the throttle valve opening. The first link 44 connected to the first lever 36 pulls the arm 43m of the second crank lever 43 and moves upward while gradually increasing its inclination. The second link 45 connected to the second lever 37 pushes the arm 43b on the opposite side of the second crank lever 43 and moves toward the lower blade while gradually increasing its inclination. Therefore, a rotational force is applied to both ends of the second crank lever 43, and the throttle valve shaft 8.10.12 of the second set of carburetors 2.4.6 is
is rotated in the direction of arrow B. When reducing the opening of the throttle valve, use the second crank lever 43.
The first link 44 pushes and the second link 45 pulls. If the two links 44 and 45 are both arranged near the idle opening position and perpendicular to each throttle valve shaft 7...12, the throttle valve will close in the low speed rotation range where the amount of intake air of the engine is small. can be made to have exactly the same opening amount, and the inconvenience of losing the balance of engine torque or making the rotational speed unstable can be avoided. Furthermore, when the first crank lever 39 is configured as shown in the illustrated embodiment, the first spring 42a and the second spring 42b rotate the two levers 36, 37 in the same direction, for example, in the direction of fully closing the throttle valve, and rotate the two levers 36, 37 in the free direction. This simplifies assembly work and adjustment work to eliminate dimensional errors by restricting rotation so as not to rotate. However, the first crank lever 39 is composed of a single piece, and its installation on the throttle valve shaft 9 depends on the angle and each link 44.4.
By making the length of the throttle valve 5 adjustable, the two sets of throttle valves 13, 15.17 and 14.16° 18 can be opened and closed in synchronization. (Effects of the Invention) According to the present invention, two of the sets consisting of a plurality of carburetors whose throttle valves are opened and closed in synchrony by a parallel rank mechanism are arranged so as to face in the intersecting direction of the throttle valve axes of each set. In this case, the crank screws fixed to one throttle valve shaft in each group are connected by two links placed on both sides of each throttle valve shaft, so that the connection from one throttle valve shaft to the other When rotation is transmitted to the throttle valve shaft, rotational force is applied to both sides of the throttle valve shaft, allowing the two sets of parallel rank mechanisms to operate in perfect synchrony with a small force without bending the throttle valve shaft. It can be linked to. In addition, by arranging the two links perpendicular to each throttle valve shaft in the low opening range of the throttle valve, the throttle valves will be held at exactly the same opening in the idling to low speed range of the engine, allowing the engine to rotate stably. be able to.
