Abstract
Some fluid couplings, as described in this document, have an actuatable valve. In some examples, the actuatable valves provide an unobstructed flow path when switched to the “open” position and a closed flow path when switched to the “closed” position.
Claims21
A selectively actuatable shut-off valve comprising:
- a body termination comprising a first fluid connection end and defining a longitudinal axis and an open internal space;
- a cartridge fixedly coupled to the body termination within the open internal space;
- a collar rotatably coupled to an outer diameter of the body termination, the collar comprising one or more protrusions;
- an insert termination comprising a valve member and a second fluid connection end, the insert termination defining one or more grooves extending around and along the longitudinal axis, wherein each protrusion of the one or more protrusions is slidably coupled within one groove of the one or more grooves;
- and
- a flexible bellow located within the open internal space and comprising:
- (i) a first end attached to the cartridge and (ii) a second end attached to the insert termination, wherein the second end of the bellow is radially spaced apart from an inner wall surface of the body termination.
