ABSTRACT:
The present invention comprises an electromagnetically operated hydraulic valve device (10) providing an almost instantaneously responsive displacement of a ball valve (60) in order to effect fluid flow relative thereto. Hydraulic valve device (10) comprises a generally cylindrical housing (12) having one end (16) open and a bushing (19) extending from the other end (18), with a plurality of longitudinal openings (14) disposed about the perimeter of housing (12). A cylindrical bobbin (30) having an interior through opening (32) is disposed within housing (12) and supports an electrical winding (34), with a core member (20) enclosing the open end (16) of the housing and having a circular post (22) extending into the bobbin opening (32). A nonmagnetizable sleeve (38) is located within the interior of bushing (19) between the bushing and a cylindrically shaped armature (36). One end (37) of the armature has an opening disposed opposite a complementary shaped opening (21) in the end of post (22), a spring (39) being received therebetween. An outer valve casing (40) is disposed over housing bushing (19), the outer valve casing having an interior cavity (45) with a groove (48) disposed in the wall of cavity (45). An inner valve casing (70) having a circumferential boss (74) about the perimeter of the casing is fitted within the interior cavity (45) by means of a leak resistant, snap-together engagement of the circumferential boss (74) and groove (48), and a glass ball valve (60) is captured within a subinterior cavity (75) in the inner valve casing. Ball valve (60) is held in sealing engagement with valve seat (45) by means of a free-floating drive pin (50), the other end of drive pin (50) abutting against armature (36). Energization of winding (34) effects an almost instantaneously responsive displacement of armature (36) whereby ball valve (60) is displaced and engages valve seat 72, relative to valve seat (45) and fluid flow effected thereby.
