Patent ID: 8690120

Claim:
A fluid transfer device, comprising: a body comprising: a first section having a groove on a surface and a first end containing a first opening and a flange surrounding the first opening for attaching the body to a process component; a second section rotatably engaged with the first section and having a second end containing a second opening; and a bore located in the interior of the body connecting the first and second openings; a linearly movable plunger movable between a closed position corresponding to a closed position of the device and an open position corresponding to an open position of the device, the linearly movable plunger being contained within the bore and having, a groove, a first portion containing a first opening and a bottom end, wherein the bottom end being in alignment with the flange surrounding the first opening of the body forms a fluid-resistant seal and a steam sterilizable face, a second portion containing a second opening, a fluid channel located in the interior of the plunger connecting the first and second openings of the plunger, and a component for inhibiting rotation of the plunger within the bore during actuation of the device; and a linear or gland seal arranged along a length of the plunger between the first opening of the plunger and the second opening of the plunger, a first portion of the linear or gland seal being retained within the groove on the surface of the first section of the body and a second portion of the linear or gland seal being retained within the groove on the plunger in sealing contact with the plunger and an inner surface of the first section of the body, wherein the plunger is linearly movable between a closed position and an open position by rotating the second section of the body; the device is in the closed position when the bottom end of the plunger is in alignment with the flange surrounding the first opening of the body; and the device is in the open position when the bottom end of the plunger is not in alignment with the flange surrounding the first opening of the body.
