Description

[Detailed Description of the Invention] This invention relates to a tsuyuel filter for separating dust, moisture, etc. from fuel.

Conventionally, a tsuyuel filter is installed in the middle of a hose that extracts fuel such as gasoline from the fuel tank using a fuel pump and sends it to the engine's carburetor. However, as shown in Fig. 1, conventional TSUEL filters have a water drain plug 2 that can be opened and closed at the bottom of the TSUEL filter container 1. Ta.

However, since this Tsuyuel filter is installed inside the engine room of a car, if the water drain plug 2 is installed at the bottom of the filter, it may interfere with other engine parts (indicated by the chain line A in the drawing). This may make it difficult to reach the water drain plug 2, which may impede water draining work, or the lower part of the filter may be hidden and difficult to see, making it difficult to check the condition of the plug 2 after draining. There was a problem.

This idea was created in view of the problems mentioned above.
A discharge port is formed at the bottom of the filter container, and an operating rod is slidably provided above the discharge port, penetrating the container vertically and protruding upward from the container lid. A stopcock that always closes the opening is provided, and a spring member is interposed between the container lid and the container lid so that the lower end of the operating rod is at a position facing away from the stopper. It is an object of the present invention to enable the draining operation to be easily and reliably performed by configuring the opening/closing valve to be opened and closed by a one-touch operation of pressing the upper part of the operating rod downward from the outside of the container.

Hereinafter, embodiments of this invention will be described based on the drawings.

2 and 3 show a first embodiment of the present invention, in which 1 is a cylindrical filter container, and the upper part of this container 1 is used to send fuel such as gasoline from a tank (not shown) to an engine, etc. A pipe 3av3b for this purpose is connected.

Reference numeral 4 denotes an umbrella-shaped filter element disposed above the inside of the container 1. A reservoir section 1a for separated moisture, etc. is provided at the bottom of the container below the filter element 4. While the fuel flowing down from above hits this filter element 4 and goes around, moisture etc. in the fuel is separated and collected in the lower reservoir portion 1a.

Further, a drain port 5 is formed at the bottom of the container 1 at a position slightly outside the center, and this drain port 5 communicates with a drain hose 6, and the lower end of this drain hose 6 is exposed to the atmosphere. It's open.

Further, above the drain port 5, an operating rod 7' whose center line coincides with the drain port 5 and which vertically penetrates the container 1 and whose upper end protrudes above the lid portion 1b of the container 1 is disposed. It is set up.

In FIG. 3, 12 and 13 are a float and a reed switch to detect the amount of water accumulated in the reservoir 1a, and a magnet 14 is disposed inside the float 12 to detect the amount of water accumulated in the reservoir 1a. When the water level in 1a reaches a certain level or higher, the float 12 rises, the reed switch 13 is turned on, and an alarm lamp (not shown) is turned on.

In this embodiment, the reed switch 13 is connected to the lid part 1b of the container.
The connection of the lead wire 16 is also facilitated by disposing the lead wire 16 in the support 15 hanging down from the container 1 and passing the lead wire 16 through the support 15 and pulling it out above the container 1.

A valve holder 21 is fitted into the drain port 5 formed at the bottom of the container 1, and a valve body 22 and a spring 23 for biasing the valve body 22 upward are arranged in the valve holder 21. At the same time, above the valve body 22, the operating rod 7' is attached so as to be slidable in the vertical direction with the container lid 1b, and the flange 7b at the upper end of the operating rod 7' and the lid 1b are connected. A spring 24 is inserted between the valve holder 21 to constantly urge the operating rod 7' upwardly, and the lower end of the operating rod 7' is connected to the upper end 22a of the valve body 22 protruding from the valve holder 21 with a slight gap. They are facing each other.

Therefore, when the operating rod 7' is pushed in from above the container 1 against the spring 24, the spring 23 is compressed and the valve body 22 is pressed downward, opening the valve and draining the water inside the container 1. It is discharged from the mouth 5 by a one-touch operation.

Also, when you release your hand from the operation lever 7', the operation rod 7' and the valve body 22
The restoring force of the springs 24 and 23 increases and the exhaust port 5 is closed.

As explained above, this invention forms a drain port at the bottom of the filter container, and above the drain port there is a freely slidable operating rod that penetrates the container vertically and projects upward from the container lid. a spring member disposed in the drain port, with an on-off valve that always closes the drain port; and a spring member that biases the operating rod upward so that the lower end of the operating rod is at a position facing away from the on-off stopper. is inserted between the filter container and the container lid, and the opening/closing plug can be opened and closed by a one-touch operation of pressing the upper part of the operating rod downward from the outside of the container. Even in cases where you cannot reach parts due to interference, the operation lever for opening and closing the water drain valve protrudes above the container, making it extremely easy to drain water. This has the effect that it can be easily checked whether the tightening has been done reliably after the completion of the pulling operation.
