Abstract

PURPOSE: To provide a buffer device of a pump without movable parts by providing an inflow conduit and an outflow conduit for a medium, and providing a plurality of compressible containers filled with a gas in an outer container closed in every side. CONSTITUTION: In a buffer device of a pump for intermittent feed such as reciprocal pump and a diaphragm pump, an outer container 1 closed in every side is provided an inflow conduit 2 and an outflow conduit 3 for a medium to be fed, and a hollow chamber in the outer container 1 is hand-accessible through a screwed lid 4. A plurality of compressible containers 5 filled with a gas, for example, film bags filled with air, are provided in an inner-chamber of the outer container 1. As a result, an impact can be buffered without providing movable parts.

In order to dampen the shocks and thus to equalize the flow, several devices are known in which the pressure shocks of the pump are compensated by means of a spring-loaded diaphragm. There are practical drawbacks to cleaning and maintaining the moving parts of such equipment.

それ故本発明は、その構造が簡単で、特に可動部分を備
