ABSTRACT:
A fluid injector unit, functioning as a pump-type injector unit through cooperation between an upper and lower press platen, being easily disassembled into a minimum number of parts for cleaning. Disengagement of a unitary assembly comprising a piston collar for supporting a main piston through biasing means therefor from a housing member containing a pump chamber results in easy access to those parts requiring cleaning without disassembly of parts external to fluid passages which do not require cleaning.
