  • Patent number: 10494899
    Abstract: A bypass valve comprising a valve body, a valve member, and a valve seat. The valve body has a first end, a second end, a central axis therebetween, an inlet formed through the first end, a valve channel, and an outlet channel extending from the valve channel to an outer surface of the valve body. The valve channel has a first end in fluid communication with the inlet, a second end terminating within the valve body, and a central channel axis therebetween which is axially aligned with the central axis. The valve member is substantially-spherical and movably disposed within the valve channel. The valve seat is disposed adjacent the first end of the valve channel. The valve seat has an orifice defined therethrough. The valve member is movable between a first position, engaging the valve seat to substantially seal the orifice, and a second position adjacent the second end of the valve channel to permit fluid to flow through the orifice.

  • Patent number: 10488232
    Abstract: A rotameter includes a rotameter body including an inlet, an outlet, and a flow channel that provides fluid communication between the inlet and the outlet. A valve for controlling fluid flow through the inlet includes an actuator rotatable about a first axis. The actuator includes worm gear threads. The valve also includes a valve drive element rotatable about a second axis that extends transverse to the first axis. The valve drive element includes worm gear teeth that mate with the worm gear threads on the actuator so that rotation of the actuator about the first axis imparts rotation of the valve drive element about the second axis. The valve drive element further includes first screw threads that rotate with the valve drive element about the second axis. The first screw threads are configured and arranged to mate with and engage second screw threads to cause linear movement of a valve component along the second axis in response to rotation of the valve drive element.

  • Patent number: 10487486
    Abstract: A flush valve has a relief valve including a stationary relief valve housing and an axially-translatable valve element. The axially-translatable valve element has an axial end that can be selectively translated to unseal an upper opening in a relief passageway through the stationary relief valve housing in order to permit fluid flow therethrough in order to initiate a flush cycle by the lifting of a diaphragm assembly. The axially-translatable valve element may include lead screw-like features which can be used to axially drive the axially-translatable valve element relative to the stationary relief valve housing to open or close the relief valve.
