ring or the like can be employed in proximity to the poppet seating location relative to the fluid inlet and to provide a fluid tight arrangement in the closed seated position referring now to fig6 an exploded view is shown at in cutaway of a further variant of the present invention and whereby a modified one piece body see as further generally referenced at 42 is incorporated into a pressure relief valve arrangement in particular the relief valve includes a rotatably adjustable cap 44 see further hex head adjustability at 46 an end of the one piece body 42 is abuttingly seated see at 47 against an inside end wall location of the first relief valve component e g cap 44 a further body portion of the relief valve is shown at 48 and which includes an inlet 50 and an outlet 52 associated with a typical pressure relief arrangement a normal fluid flow line is as is conventionally known but not illustrated herein in communication with the fluid inlet 50 the one piece inner valve seating body 42 according to the pressure relief variant differs in some respects from that previously described at 12 in the check valve variant in particular in that the body 42 does not provide for fluid flow relative to its axially extending length rather the body 42 includes an annularly rounded reduced diameter forward end 52 corresponding to a poppet seating location an intermediate plurality of helically machined or otherwise formed coils 54 are also provided unlike the variant 12 in fig1 the one piece body 42 does not include additional exteriorly configured adjustment threads rather the function of spring pre adjustability is.
