FLUID INLET DEVICE FOR FEEDING A FLUID INTO A PISTON PUMP

摘要

PURPOSE: An apparatus for supplying fluid into a piston pump is provided to prevent a turbulent flow by vertically supplying fluid to a piston pump through the apparatus. CONSTITUTION: An apparatus(42) for supplying fluid to the into a piston pump comprises one or more inlet grooves(44), webs(46), and a shoulder unit. The inlet grooves are formed in the axial direction of a piston(16). The webs are arranged next to the inlet grooves and have elasticity. An internal step and an external step(52) are formed in the shoulder unit. The webs are arranged on the internal step inserted into a hollow chamber(54) of the piston.
