Abstract

PURPOSE:To enable the checking of a fuel oil face simply without working a float chamber considerably. CONSTITUTION:A screw hole 5 is penetrated through an upper wall face 2' of a float chamber 2 then fastened with a screw 6 while a transparent pipe 7 is held dismountably at the lower end section of the screw 6. A float chamber upper wall matching mark A and a regular oil face mark B are marked on the pipe 7. When confirming the oil face, the screw 6 is first removed from the upper wall section 2' then said mark A is matched with the upper wall section 2'. Thereafter the upper end of the pipe 7 is sealed tightly by a finger and lifted as it is. Consequently the fuel oil face can be seen as it is. When comparing this oil face with said mark B the fuel oil face level can be known.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carburetor that allows easy confirmation of the oil level in the float chamber of the carburetor.

Conventionally, oil level confirmation devices have not been given much importance because the oil level in the carburetor float chamber is checked only when the carburetor is assembled or during specific maintenance work.

The conventional way to check the oil level is to drill a long hole in the carburetor 11m111SK, and use the so-called oil rT, which is made by gluing a transparent plate to the long hole.
There were cases where it was executed by JflK. Vaporizer flow) liK such an oil level j! Even if it is installed, if the oil level cannot be clearly confirmed depending on the position of the carburetor, it is preferable from a safety point of view to provide a hole in the float chamber of the carburetor. do not have.

In such a carburetor without an oil level window, the oil level was checked by removing the drain plug provided at the bottom of the float chamber and attaching a special tool for checking the oil level. This type of work cannot be considered as efficient oil level checking work.

However, in order to efficiently perform the function of the vaporizer:
t) Setting the oil level in the float chamber at the appropriate position is an essential and important matter.

An object of the present invention is to provide a carburetor equipped with a device that can efficiently and accurately check the oil level in a float chamber.

This will be explained below with reference to the drawings.

FIG. 1 is a schematic diagram showing an embodiment of a carburetor to which the present invention is applied, and an IT variable venturi disk carburetor is shown as an example, but it can also be applied to a fixed venturi venturi disk vaporizer. . In the figure, 1 is the carburetor main body, and 2 is the float chamber. As is well known, fuel 3 is supplied into the float chamber 2, and a 7-day float 4 is used to maintain the oil level at a constant level.

A screw hole 5 is made to pass through the earthen wall portion 2' of the float l[2.

A screw 6 is screwed into this screw hole 5, and the lower 11 portion 6' of the screw 6 has a smaller diameter than the threaded portion 2'.
It is centered downwards. A transparent pie is removably held at this lower end.

2nd m! ! Figures 3 and 3 show an example of checking the oil level using the transparent pipe 7. Attach the float seal to the upper wall of pipe 7! - Attach the rim and regular oil level mark l.

When checking the oil level, first remove the screw 6 from the upper SZ/, then remove the screw 6 and pipe 7. As shown in No. 31m1, match the float room soil wall! - Align the rim to upper 1isz'. Then seal the top end of the pipe 7 in that position with your finger and lift it so that the fuel oil level is visible in the pipe 17. You can know the fuel oil level by comparing this oil level with the regular oil level mark. After completing the work, screw the original IIK screw 6 again.

In the above embodiment, the screw 6 was fitted to the top 11112'Klt, but the hole 9 of the screw 6 was fitted into the hole drilled in the top part of the AT, which can withstand temperature changes around the carburetor and has sealing ability. You can also.

As described above, the present invention has the effect that it is possible to easily check the fuel oil level without extensive modification of the float.
