Cam controlled double acting piston slide pump - used to measure out high viscosity liquids and fitted with oscillating and rotating piston

摘要

Cam controlled double acting rotary piston slider pump equipped with an oscillating and simultaneously rotating piston. The piston is flattened off both front and rear end. The flattening is arranged so that the control slot may be selectively opened in the pressure pipe and closed in the suction pipe. During forward movement the piston conveys the medium into the pressure pipe until reaching front dead centre and at the same time sucks the medium in the rear section of the cylinder section. the same process is repeated during the return movement. The pump pemits closing of prods. of high viscosity such as emulsions etc. in equal quantities ensured by the double piston system.
