本発明は、ベーパライザ内のタールを排出するためのド

ある。For example, in an engine that uses liquefied gas as fuel, such as an LPG engine, the liquefied gas is once depressurized and vaporized in a vaporizer, and then supplied to the engine combustion chamber through a mixer. A considerable amount of tar accumulates within the vaporizer, particularly in its secondary chamber, and there is a strong possibility that this tar may adhere to the diaphragm of the vaporizer or enter other operating parts and impede the function of the vaporizer.

りがちである。For this reason, conventionally, as shown in Japanese Utility Model Application Publication No. 50-153312, a drain device is attached to the secondary chamber of the vaporizer, and the tar in the secondary chamber is drained externally by manual operation of the drain valve. I was trying to drain it. However, with this conventional drain device, if you forget to close the drain valve and the pulp is left open, the vaporized fuel in the secondary chamber will leak out through the drain valve during engine operation. This was causing a dangerous situation. Liquefied gas engines are particularly frequently used in taxis, and in taxis, the above-mentioned drain pulp is operated to remove tar after the day's work is finished, so the drain pulp must be opened and closed almost every day. However, it is common for people to forget to close the drain pulp after discharging the tar.

装着部から気化燃料が洩れる問題がある。Furthermore, the above-mentioned Japanese Utility Model Application Publication No. 50-153312 also discloses a drain device that is provided with a spring that biases the valve body of the drain pulp in the valve closing direction so that the drain valve remains closed at all times unless acted upon by an external force. However, this type of drain device still has the problem of vaporized fuel leaking from the mounting portion of the container 23 unless the container 23 is completely sealed or removed after the tar is removed.
本発明は上述のような問題を解消した、ベーパライザの
ドレン装置を提供することを目的とするものである。An object of the present invention is to provide a vaporizer drain device that solves the above-mentioned problems.
本発明のベーパライザのドレン装置は、ドレン通路ニ、
ドレンパルプ、おヨヒエンジン停止時に開く開閉弁を直
列に介設したことを特徴とするものである。The vaporizer drain device of the present invention includes a drain passage, a drain passage, and a drain passage.
It is characterized by having an on-off valve in series that opens when the drain pulp and oyohi engines are stopped.
上記のような構成により、たとえドレンノくルブが開い
たままであってもエンジンを始動すれば開閉弁が閉じ、
ドレン通路から燃料が外部に洩れることが防止される。With the above configuration, even if the drain valve remains open, the on-off valve will close when the engine is started.
Fuel is prevented from leaking to the outside from the drain passage.

The secondary chamber 4 and the secondary chamber 5 are communicated with each other by a communication passage 8 formed in the partition wall 3. The opening degree (valve opening pressure) of the LPG population 6 is adjusted by a ceiling 10 that interlocks with the -order diaphragm 9.
Further, the opening degree (valve opening pressure) of the communication passage 8 is adjusted by a secondary valve 13 which is interlocked with the secondary diaphragm 11 and also controlled by the lock-off diaphragm 12. Since the structure and operation of such a vaporizer itself have been well known, further detailed explanation will be omitted.

An electromagnetic on-off valve 26 of the type that closes when energized is opposite to the electromagnetic on-off valve 26, and a manually operated drain pulp 27 is provided on the downstream side (atmospheric side) of the electromagnetic on-off valve 26. The drain pulp 27 used in this embodiment includes a rotary valve body 27a and an operating lever 27 that projects from the rotary valve body 27a in the radial direction.

As shown in FIG. 2, this sensor 28 includes a contact switch 29 fixed near the drain valve 27, a support arm 30 extending radially from the rotary valve body 27a, and a support arm 30 that is screwed into the support arm 30. It is composed of a screw 31 that is fitted together and a coil spring 32 that prevents the screw 31 from rotating. When the drain valve 27 is completely closed as shown in FIG. 2, the tip of the screw 31 presses the actuator 29a of the switch 29 to close the switch 29. Further, by threading the screw 31 forward and backward relative to the support arm 30, fine adjustment is made so that the switch 29 is closed only when the drain valve 27 is in a completely closed state.

and a pilot lamp 36 are connected in series with each other, and a second switch 37 and a solenoid 16a of an electromagnetic on-off valve 160 are connected in series with each other in parallel with the first switch 35 and pilot lamp 36. Further, a solenoid 26a of the electromagnetic on-off valve 26 is connected in parallel to the second switch 37 and the solenoid 16a. The first and second switches 35 and 37 are controlled by the sensor 18, and when the drain valve 27 is fully open or partially open (that is, not completely closed), the first switch 35 is closed and the second switch is open. Conversely, when the drain valve 27 is completely closed, the first switch 35 is opened and the second switch is closed.

ンバルブ２７の開閉いかんにかかわらず閉状態を保つ。The operation of the apparatus of this embodiment having the above configuration will be explained below. First, when the engine is operated with the drain valve 27 completely closed and the ignition switch 34 turned on, the first switch 35 is opened and the second switch 37 is closed, so the pilot lamp 36 goes out and the electromagnetic on-off valve 16 is turned off.
is open. On the other hand, since the electromagnetic on-off valve 26 and the high-pressure switch 34 are turned ON, the closed state is maintained regardless of whether the drain valve 27 is opened or closed.

Pass through 0 and enter primary room 4. When LPG passes through the ceiling 10, the pressure is reduced to a level slightly higher than atmospheric pressure.

LPG passes through the LPG outlet lower from the secondary chamber 5 and is supplied from the fuel supply port 20 of the mixer 19 to the engine combustion chamber (not shown).

二次室５内のタールが外部に排出される。As LPG is supplied as described above, tar accumulates in the secondary chamber 5 within the vaporizer 1. The tar accumulated in the secondary chamber 5 is discharged to the outside by opening the drain valve 27 with the ignition switch 34 turned OFF and the engine stopped. That is, by turning off the ignition switch 34, the electromagnetic on-off valve 2
6 will open, so if you open the drain valve 27 manually,
The tar in the secondary chamber 5 is discharged to the outside.

Therefore, even if the drain valve 27 is partially opened due to forgetting to close the tren pulp 27 after discharging tar, LPG will not leak to the outside from the drain passage 25a. At the same time, if the drain valve 27 is not completely closed, the second switch 37 will open and the electromagnetic on-off valve 16 will open.
is closed and LPG is not supplied to the vaporizer 1, so that LPG leakage can be more reliably prevented. Further, as described above, if the drain valve 27 is not completely closed, the first switch 35 closes and the pilot lamp 36 lights up to notify the driver of this fact.

For example, an alarm buzzer or the like may be used instead of the pilot lamp 36, and the electromagnetic on-off valve 26 may be replaced with a drain drain. It may also be provided downstream of the valve 27. In addition, warning means such as a pilot lamp 36 (
Of course, the first switch 35) and the electromagnetic on-off valve 16, which are provided together with this, do not need to be provided.
