Embodiment Construction

[0047] figure 1is a cross-sectional view of a rocker valve 100 according to an embodiment of the invention. The rocker valve 100 includes a valve body 110 including a chamber 112, a removable port portion 120, a rocker valve mechanism 130 at least partially within the chamber 112, a flexible sealing member 140, and an actuator 150. .

[0048] The port portion 120 includes a first fluid port 121 , a second fluid port 122 , and a third fluid port 123 . Such as figure 2 As shown in more detail in , the first fluid port 121 communicates with the first valve seat 124 and the second fluid port 122 communicates with the second valve seat 125 . The rocker valve mechanism 130 can selectively block and unblock the first fluid port 121 and the second fluid port 122 and thereby regulate fluid flow. The first fluid port, the second fluid port, and the third fluid ports 121 to 123 are separated by predetermined intervals. Port portion 120 may be removably attached to valve body 110 . ...

Abstract

The present invention provides a rocker valve comprising a valve body including first and second fluid ports; and a rocker valve mechanism in the valve body. The mechanism comprises a single pivot armrotatable relative to the valve body, and first and second plungers pivotally fixed to the single pivot arm. The second plunger acts in opposition to the first plunger when the single pivot arm is pivoted relative to the valve body. The rocker valve includes a flexible seal member extending laterally across the first and second fluid ports. The flexible seal member has a first sealing region attached to the first plunger and a second sealing region attached to the second plunger and is movable by the first and second plungers between a first position in which the first fluid ports is closed by the first sealing region, and a second position in which the second fluid port is closed by the second sealing region. When the single pivot arm is pivoted relative to the valve body, a rotation ofat least one of the first and second plungers about its respective fixed pivot is constrained solely by the flexible seal member.

Description

technical field [0001] The present invention relates to a rocker valve including a rocker valve mechanism. In particular, the present invention relates to rocker valves that include a plurality of fluid ports and a rocker valve mechanism that is movable to control fluid flow through the fluid ports. Background technique [0002] Valve mechanisms are used to control the flow of fluids, such as fluids under pressure. Valves generally include a valve body defining a plurality of ports and a valve mechanism movable within the valve body to direct fluid flow in a desired manner by selectively opening or closing one or more of the ports. Execute the valve function. One known type of such valve is the rocker valve. A rocker valve typically includes a valve body within which a rocker valve mechanism is pivotally mounted to alternately open and close a pair of fluid ports when pivoted between end positions. [0003] US Patent No. 2,935,086 discloses a pilot operated valve compris...
