The ends of the tubular spool I extend out It is to be understood that I am not restricted to the specific construction shown anddescribed as various modifications can be made thereto within the spirit of the invention.

What is claimed is:

1. In a device of the character described the combination of an open-ended tubular spool of non-magnetic -'m'ate rial defining a fluid passage way, a solenoid coilwound about said spool, a cylindrical casing enclosingsaid coil, said casing having an inturned annular flange about each end thereof, a closure disc disposed in each-end of said casing between said coil and said inturned flanges, each of said closure discs having a cenpassageways fornr an integral part thereof, a solenoid" plunger disposed within said tubular "spool, and a valve plunger which is adapted to "engage the inner end of one of said fluid passagetral aperture therethrough throughwhich said I tubular spool extends, a cap removably secured to each of said closure discs with said flanges interposed between said caps and said discs, an annular groove in the inner face of each of said caps into which the ends of said tubular spool extend, "coupling means by which said device is interposed in a conduit so that said spool forms .ai-part thereof, .a solenoid plunger mounted within said spool,'-a;-valve plunger secured to said. solenoid plunger, and a valve seat formed in one of said caps in which said valve plunger is adapted to-seat to close said fluid passageway.

"2, Inadevice of the character described the combination of a solenoid coil having'an axial bore therethrough, a cylindrical easing having an inturned annular flange at each end thereof surrounding said coil, "a pair of identical closure 'discsf-each having a: central aperture there through, one of said discs-being disposed in each end of said casing between said coil and the adjacent inturned flange with the central aperture thereof in alignment with the axial bore in said coil, a pair of identical caps each having a central fluid passageway therethrough, one of said caps being removably secured to each of said closure discs with the adjacent inturned flange securely clamped between the cap and closure disc, an open-ended tubular spool removably v mounted in said axial bore with the ends thereof extending out through the apertures in said discs :and 'intorgas-tight engagen'ientgwith said caps around said-fluid passageways-coupling means by which said device is removably interposed in a fluid conduit so that said spools and said fluid ways and cut o'if the flow of fluid through said spool carried said solenoid plunger.
