Valve with multiple cylindrical portions and piston
The granted patent US12044330B2 describes a valve designed with a multi-part housing structure that includes three hollow-cylindrical portions of varying diameters. The first portion has the largest outer diameter, followed by a second portion with a smaller diameter, and a third portion that is even smaller. The valve features a first opening on one end and at least one second opening in the second portion, with the third portion surrounding the first opening. Additionally, the design allows for a piston to be located within the housing, which can move axially to control the openings. The patent also specifies that multiple second openings can be distributed around the circumference of the second portion, with options for uniform separation or axial offset between them.
Further claims detail the structural features of the valve, including the presence of steps on the outer circumference where the cylindrical portions merge. The valve is intended for use in a device that controls the pressure of a flow medium, with the valve being partially seated in a component and the second openings leading into an annular gap surrounding the valve. This gap can be sealed with at least one seal, and the design includes fluidic connections between channels and openings to facilitate the flow of the medium. Overall, the patent outlines a comprehensive design for a valve that emphasizes structural integrity and functional versatility in pressure control applications.
