  • Valve components and method of assembly therefor
    Patent number: 10288176
    Abstract: The invention provides a method of, and means for, connecting components of a moveable sub-assembly in a fluid control valve. To control a dimensional characteristic of the moveable sub-assembly, a first component of the sub-assembly can be crimped to create a mechanical connection to a second component of the moveable sub-assembly. The sub-components may be configured such that in the absence of the crimp they can be moveably translated between a plurality of positions and they may be slideably translatable between a number of relative positions, while the crimp acts, once formed, to retain the sub-components in a chosen position relative to one another.
    Type: Grant

  • Rocker valve mechanism and rocker valve
    Patent number: 8752584
    Abstract: A rocker valve mechanism (125) is provided according to the invention. The rocker valve mechanism (125) includes a port portion (110) including a plurality of ports (113-115), a first plunger (130), and a second plunger (131) acting in opposition and moving substantially in parallel with the first plunger (130). The rocker valve mechanism (125) is biased toward a first position blocking a third port (115) and configured to be actuated to a second position blocking a first port (113).
