Abstract: According to the invention, multiple-cylinder internal combustion engines comprise a lifter oil manifold assembly (LOMA) positioned in an improved and beneficial manner. In one embodiment, engines of the invention comprise an engine block comprising a V-valley in which the LOMA is mounted such that longitudinal axes of the plurality of solenoid control valves therein are positioned essentially perpendicular to a vertical axis centrally extending from an angle formed by the V-valley of the engine block. In another embodiment, V-valley of such an engine not only comprises a LOMA but also includes a balance shaft.

Abstract: A solenoid operated valve has first flux collector, bobbin with coil and an armature assembled onto a valve body with a tubular housing received over the body and first portions of the housing, in the form of tabs, deformed over the bobbin flange to retain the assembly. A second flux collector with adjustable pole price is then assembled adjacent the bobbin and retained in place by deformation of second portions of the housing. The pole piece is accessible exteriorly for adjustment through the end of the housing.

Abstract: A lead frame has slots therein for bayonet type connection to electrical terminals provided on a solenoid valve or group of valves. Projections on the lead frame are disposed between the slots and upon bayonet connection to the terminals closely interfit a web disposed between the terminals on the solenoid. Preferably, support stanchions are provided for the terminals and may be integrally molded with the web.
