Abstract

PURPOSE:To prevent environmental contamination and noise by setting an air filter which also serves as a silencer, at the exhaust outlet of an air motor (air cylinder) to drive a pneumatic pump for pain supplying, whereby lube oil is separated to be returned to the oiler. CONSTITUTION:The paint in a pain container 6 is supplied to a paint spray gun 9 with a drive by a pneumatic paint pump 1 having a piston 4 making reciprocating motion by a double acting air cylinder 10. An air cylinder 11 is driven by the compressed air pumped from a compressed air source 13 through a 5-port-2- point changeover valve 16. The mobile piece of the changeover vave 16 has a position holding mechanism 18 and said mobile piece is connected to a piston rod 19 via an elastic body 20. The outlet of the changeover valve 16 is led to an air filte 23, which also serves as a silencer, through an air chamber 21. A small pneumatic pump 27 whose outlet is connected to an oilder 15 is connected to the bottom of the filter 23.

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).
