4TK Air-Oil Tanks provide a means to convert shop air pressure into hydraulic pressure. Compressed air is applied directly to the oil in the air-oil tank to convert it into hydraulic pressure. The hydraulic pressure is at a 1-to-1 ratio, i.e. 80 psig air produces 80 psig hydraulic pressure. All Parker Air-Oil Tanks have a fiberglass tube which shows the proper oil level. They also contain two fluid flow baffles. The top baffle disperses the incoming air over the surface of the oil in such a way to avoid agitation and aeration. The bottom baffle insures a smooth flow pattern that minimizes oil turbulence and eliminates swirling, funneling or splashing which, in turn, could cause oil aeration or the oil to be blown from the tank into the exhaust air. Air-Oil Tanks are used to smooth out the cylinder piston rod travel and to prevent chatter. They are mainly used in slow speed circuits.
