Fluid handling components
This document describes devices and methods for reducing liquid spillage, such as fluid coupling devices that include one or more apertures that reduce spillage when the fluid coupling devices are disconnected. In some embodiments, the one or more apertures are designed with features to increase a level of acceleration that liquid within an internal volume of the fluid coupling devices would need to be exposed to in order to spill from the internal volume via the one or more apertures.
1. An anti-spillage poppet valve fluid coupling device, comprising:
a first coupling body member configured to mate with a second coupling body member and defining a longitudinal axis and an interior space defined by an inner sidewall between a first port and an opposing second port; and
a first poppet valve assembly disposed at least partially within the interior space, the first poppet valve assembly comprising:
a first closure member having: (i) a forward end region, (ii) a rear end region, (iii) a piston head proximate the forward end region and (iv) a sealing surface proximate the rear end region, the first closure member longitudinally movable within the interior space between: (a) a closed position in which the sealing surface prevents fluid communication between the first port and the second port, and (b) an open position in which the first port and the second port are in fluid communication,
the piston head having a circular outer circumference,
the piston head defining two or more apertures extending longitudinally through the piston head, and
wherein a face of the piston head defines grooves such that each of the two or more apertures is surrounded by a groove.
2. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein each of the two or more apertures are partially defined by an annular lip that projects radially inward.
3. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein wall surfaces defining each of the two or more apertures are textured, thereby increasing a wettability of the wall surfaces defining the two or more apertures.
4. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein the two or more apertures comprise at least two apertures.
5. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein the two or more apertures comprise at least three apertures.
6. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein at least one of the two or more apertures is circular.
7. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein at least one of the two or more apertures is generally triangular.
8. The anti-spillage poppet valve fluid coupling device of claim 1 , wherein the two or more apertures includes three generally triangular apertures.
