[15] The present invention relates to a solenoid operated hydraulic valve mounted as part of a load bearing device such as a damping rod used in automotive suspension. Solenoidally actuated hydraulic valves used for such applications are subject to cyclical tension and compressive loads on their structural elements, and have a series of alignments along the central axis of the solenoid armature to achieve effectiveness and economics in manufacturing and assembly. Achieve.
[16] Due to the load bearing members in the suspension system, the valve additionally requires specific dimensions to have load bearing capabilities. To date, the assembly of components has finally been achieved by welding and screwing, which has proved to be enormously costly due to the high volume mass production of automotive components, particularly for passenger vehicles and light trucks. In addition, some limitations in allowable dimensional changes often require pre-assembly machining, which adds to manufacturing costs.
[17] The known valve assembly is shown in FIG. 4, wherein the first load bearing end member 1 is provided with a flow collector ring member 3 attached to the second annular body member 2 to the shoulder or body member 2. Screwed together. The load bearing member 1 has an internal threaded portion 1A formed at its upper end for attaching to the load providing member. The lower end of the body member 2 has an inlet port 6. The movable armature / valve member 4, the pole piece 5 and the potted sleeve member 7 are disposed between the members 1 and 2 before their screwing assembly. Thus, the assembly of FIG. 4 is relatively complicated by a large number of parts and combinations thereof, and the combination and assembly are relatively expensive in mass production.
[18] Therefore, it is desired to provide a solenoid operated hydraulic valve intended to function as a load bearing member, such a device being easy to assemble and install at a relatively low manufacturing cost.
[19] The present invention is used as a structural load bearing member in an assembly and includes a load bearing member on its opposite end such that an inlet port is formed therein and aligned with a load bearing bearing on a single valve body having a side port in communication with the inlet port. It provides a solenoid operated hydraulic valve having. The annular flow collector is disposed on the body, and the sleeve with the magnetically osmotic material is disposed above the side port and movable on the body to open or close the side port. The annular pole piece is disposed on the body at a distance from the flow collector and a coil of electrically conductive material is disposed around the sleeve that is moved over it when the coil is activated.
[20] In a preferred embodiment, the load bearing surface and the inlet port are arranged coaxially and are arranged such that an outlet port in communication with the side port is provided and discharged in a direction generally parallel to the inlet port. The present invention therefore provides a unique and novel load bearing solenoid operated fluid valve assembly having a single body having an inlet port formed therein for insertion as a load bearing member in a fluid operated system.
