An internal combustion engine system includes a combustion engine configured to produce exhaust gases as a product of a combustion reaction. An exhaust discharge pipe coupled to the internal combustion engine, and an adaptive valve assembly. The adaptive valve assembly is coupled to the exhaust discharge pipe and configured to receive the exhaust gases prior to the exhaust gases reaching the atmosphere. The adaptive valve assembly includes a valve flapper arranged in the passageway and configured to pivot about a flapper pivot axis from a normally-closed position to an opened position.

A fluid valve control system includes a linear actuator assembly with a linear actuator, a mechanical amplifier, and a mechanical output member; a fluid control valve, including: a valve body with a fluid chamber and an outlet aperture, a fluid supply line, a plunger member; a fluid reservoir with a pressurized fluid, and a fluid dispensing control unit; such that the fluid flows in a flow from the fluid supply line into the fluid chamber and out via the outlet aperture; such that plunger member moves vertically downward when the outer end of the plunger member is impacted by the mechanical output member, such that an inner end of the plunger member blocks the outlet aperture, such that the flow of the fluid is interrupted.

A check and flow metering cartridge valve having two flow restriction zones, each zone being disposed adjacent a respective end of a valve chamber containing a check valve member, the zones being serially encountered by flow through the valve, the restriction of the restriction zones together being a majority of the total flow restriction in the valve, each restriction zone producing at least 26% of a total restriction to flow through the valve, the restriction zones maintaining back pressure in the valve chamber when the check valve member is unseated thereby providing damping of the check valve member.

A hose end regulator for regulating pressure in fluid includes a main body having a fluid inlet and fluid outlet. A poppet moves between an open position to permit fluid to flow through the fluid outlet and a closed position to militate against fluid flowing through the fluid outlet. A primary spring permits the poppet to move between the open position and the closed position. A flow maximizer minimizes movement of the primary spring until a predetermined fluid pressure is reached within the main outer body.

An apparatus for actuating an end-member is disclosed. The apparatus includes a housing, a spring within the housing, and a spring plate forming a restriction for the spring within the housing. A brake member is associated with the spring plate for retaining the spring plate in one or more positions. A drive rod is associated with a motor to enable a first movement of the drive rod and to enable a second movement of spring plate. The first movement or the second movement enables the actuating of the end-member in one or more different positions for the end-member. The brake member may be engaged or disengaged to control or decouple spring compression forces in the actuator when the spring is compressed.

Proposed is a mixing valve, including a valve housing and a switching valve part and a proportional valve part, wherein either a common valve body or a multi-part valve body is provided for the switching valve part and the proportional valve part, and the valve body comprises a valve body part which faces the switching valve part and a valve body part which faces the proportional valve part, and the valve body is movable by an external force in opposition to the resetting force of at least one spring.
