〔実施例］ 本発明の詳細を図に示す実施例に基づいて説明する。〔Example] The details of the present invention will be explained based on embodiments shown in the drawings.
第１図において、本発明で用いる空気装置ａとして例え
ばベーン形装置を使用することができる。In FIG. 1, for example, a vane type device can be used as the air device a used in the present invention.
ベーン形装置ａは複数のベーン１を有し、該へ一ンｌは
ロータ２のスロット３に挿入される。ロータ２はケーシ
ング４内に収容され、回転中心５がケーシング４の中心
に対し偏心して配置されている。The vane-shaped device a has a plurality of vanes 1, one of which is inserted into a slot 3 of the rotor 2. The rotor 2 is housed in a casing 4, and the rotation center 5 is eccentrically arranged with respect to the center of the casing 4.
空気袋ｇａがエアモータとして働く時は、入り口６から
圧縮空気が給気され空間７に入り、隣合うベーン１とベ

が与えられる。空間７に入った圧縮エアーはロータ２の
回転に伴って回転して一次出口８より大気へ排出されて
エアモータとしての作動を完了する。When the air bag ga functions as an air motor, compressed air is supplied from the inlet 6 and enters the space 7, and rotational force is applied to the rotor 2 with a torque corresponding to the difference in area between the adjacent vanes 1 and 1'. The compressed air that has entered the space 7 rotates as the rotor 2 rotates and is discharged to the atmosphere from the primary outlet 8, completing the operation as an air motor.
一方、空気装置ａが圧縮機として作動するときは、同じ
く入り口６より空間７に吸気しロータ２の回転につれて
圧縮されて二次出口９より所定のエアタンクへ導かれる
。この時、前記の一次出口８はソレノイドバルブｌＯ１
例えば２ボートソレノイドバルブにより閉じられる。On the other hand, when the air device a operates as a compressor, air is similarly drawn into the space 7 from the inlet 6, compressed as the rotor 2 rotates, and led to a predetermined air tank from the secondary outlet 9. At this time, the primary outlet 8 is the solenoid valve lO1.
For example, it may be closed by a two-boat solenoid valve.
即ち、ソレノイドバルブ１０がエアモータとして作動す
る時は開放され、圧縮機として作動する時は閉鎖される
ことにより、一台の装置でエアモータと圧縮機との作動
に兼用されることが可能となる。That is, by opening the solenoid valve 10 when operating as an air motor and closing when operating as a compressor, it becomes possible for one device to operate both as an air motor and as a compressor.
空気装置ａへの圧縮空気の供給及び空気装置ａからの圧
縮空気の備蓄のシステムについて第２図に基づいて説明
する。A system for supplying compressed air to the air device a and storing compressed air from the air device a will be described based on FIG. 2.

口１４．１５が導管１８に接続される。The inlet 6 of the air device a is connected by a first conduit 17 to an air tank C in which compressed air is stored. Note that a first switching valve e, for example, a three-way valve such as a three-port solenoid valve, is connected in the middle of the first conduit 17. That is, the communication port 11.12 of the three-boat solenoid valve e is connected to the conduit 17. Furthermore, the outlet 9 of the air device a is connected to the air tank C by a second conduit 18. Note that a second switching valve e', for example, a three-way valve such as a three-boat solenoid valve, is connected in the middle of the second conduit 18. That is, the communication ports 14 and 15 of the three-boat solenoid valve e' are connected to the conduit 18.

5 will be closed.

The operated air is discharged to the atmosphere. Communication between the second switching valve e' and the air tank C is cut off. Further, in response to the start signal, the electromagnetic clutch d is connected, and the engine b starts rotating by the air motor a, completing the starting system.

。Next, when operating as a compressor, 1 of air tank C
When the 14M pressure drops to the set value, it is detected by the pressure switch F attached to tank C and sends a signal.
At the same time as the solenoid valve IO of the air device a is closed and switched to the compressor mechanism, the first switching valve e allows communication between the communication port 11 and the opening 13 to the air, and the communication port 12 is closed.
The second switching valve e' communicates between the communication port 14 and the communication port 15, and the opening 16 to the atmosphere is closed. Further, in response to the start signal, the electromagnetic clutch d is connected, and the driving force of the engine b is applied to the air device ffa, so that the air device a is rotationally driven.

もよい。In the embodiment of the present invention, an example using a vane type air device is shown, but the device is not limited to the vane type, and devices such as a reciprocating type and an axial type may also be used. There is no problem with the magnetic shift type pinion and ring gear meshing mechanism used in the starter, and compressed air can be used instead of electromagnetic force.

縮空気を入れてやる事は言うまでもない。After installing this starter, it goes without saying that you need to separately fill the air tank with compressed air for the first time.

必要としなくなった。According to the present invention, a single pneumatic device can be operated as both an engine starter and a compressor by simply connecting the pneumatic device to an air tank via a switching valve. In other words, the air device connected to the engine can be used as an air motor when starting the engine, and when the supplied air is insufficient, it can be operated as a compressor to fill the air tank, and special compression equipment is not required. I stopped doing that.
