Abstract
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.
Claims18
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,
- wherein a single aperture extends longitudinally through the piston head, and
- wherein a face of the piston head includes an empty groove surrounding the aperture.
