するようにしてなるのである。A special configuration of the present invention for the drive pump is such that when switching the air supply/discharge switching valve (16), it is switched instantaneously at the end of the reciprocating movement of the piston (B), that is, A position holding mechanism (e) is attached to the movable element of the switching valve (16), and the movable element is connected to the rod (to) of the piston (b) through the interposition of an elastic body. At the end of the reciprocating movement of the switching valve (16), the movable element of the switching valve (06) is rapidly driven to overcome the holding force of the holding mechanism (incorporated) in the switching valve (16), and the switch valve (16) is rapidly driven to switch. On the discharge side of ) there is a cylindrical filtration element ) with the intervention of an air chamber (21).
By connecting the ) is separated and cleaned, and at the same time, the shocking exhaust noise is silenced and discharged to the outside air, and the separated oil liquid is allowed to flow down to the bottom. A small pneumatic plunger pump (c) driven by a small air motor (c) is connected to the cylinder and its internal piston (c), and the air chamber @ is used to supply pressurized air to the air motor (c). A part of the exhaust gas of υ is introduced into a relatively thin conduit (goods), and a check valve is provided at the discharge part 4 of the pump (a), and the discharge pipe 0ρ is connected to another check valve 01. (to Euler under the intervention of)
The air motor (1o) for driving the paint pressure pump (1) cleans the exhaust air that is impulsively discharged by the air filter that also serves as a silencer, and then attenuates the impulsive noise. Instead of releasing it into the atmosphere under the same conditions, a portion of the oil is introduced into an air motor and drives a plunger pump (5) to remove the oil that has flowed down to the bottom of the filter. The oil is pumped back into the oiler 05).

るようにするのがよい。Since the exhaust from the air motor (11) is relatively high-pressure and rapid, it is necessary to lead it out to the switching valve (16) empty air chamber @υ through a large diameter flow path. C) is not led out through a single large-diameter flow path, but is led out through a plurality of conduit-rings having approximately the same diameter as the conduit to It is advisable to ensure that a portion of the pressure exhaust can be supplied to the air motor (air motor).
(効 果)
以上説明したように、本発明によれば次のような諸効果

ことができると同時に、衝撃音を伴なう排気騒音を消音
して静粛に大気中へ放出することができ、環境汚染の防
止と騒音害の防止とを一挙に実現することができる。(a) Since an air filter that also serves as a silencer is provided on the exhaust side of the air motor, it is possible to separate and collect the lubricating oil mist that is contained in the exhaust from the air motor and is led out, while at the same time eliminating the impact noise. Exhaust noise can be silenced and quietly released into the atmosphere, making it possible to prevent environmental pollution and noise damage all at once.
(b) エアーフィルターにより分離した潤滑油を駆
動ポンプによりオイラーへ還送するようにしだから、潤
滑油を回収して自動的に再利用することができる。(b) Since the lubricating oil separated by the air filter is returned to the oiler by the drive pump, the lubricating oil can be recovered and automatically reused.
(c) 潤滑油還送用駆動ポンプを排気圧により駆動
するようにしたから、格別な電動機あるいは流体源を設
