Abstract: A rapid connect coupler can include a housing, a probe configured to translate within the housing, a handle assembly configured to cause the probe to translate within the housing body, a stop assembly configured to selectively arrest the translation of the probe. The stop assembly can include: a pawl configured to occupy both an active position and an inactive position, wherein the inactive position arrests the translation of the probe; a catch fixed to the housing and configured to hold the probe in the inactive position; a lever configured to engage the pawl; a spring fixed to both the housing and the lever and configured to bias the pawl to the inactive position via the lever; and a cam configured to disengage the pawl from the catch and cause the pawl to occupy the active position.

Abstract: A fluid coupler includes: an outer body; an end connector being at least partially received inside the outer body and configured to receive pressurized fluid; an inner body received inside the outer body, the inner body being moveable with respect to the outer body; a seat holder and a valve seat both located inside of the inner body, the valve seat being configured to press against an inner surface of the inner body to close the fluid coupler; a connector partially housed within the inner body, the connector comprising a first end secured to the seat holder and a second end. The fluid coupler defines a pressurized fluid flow path enabling pressurized fluid to contact and pressurize the end connector, the inner body, the seat holder, and the connector without contacting and pressurizing the outer body.

Abstract: A relief valve configured to allow content held within a vessel to be release under pressure is disclosed. The relief valve is configured to expose a release outlet when pressure within the vessel exceeds a release pressure, and the relief valve is further configured to maintain exposure of the release outlet after pressure within the vessel falls below the release pressure.

Abstract: A relief valve coupled to a container is disclosed. The relief valve may include a valve body forming an internal chamber, an inlet portion connected to the chamber and configured to receive content flow from the container, a spring, a poppet including a seat disc, wherein a spring force exerted by the spring biases the seat disc towards the inlet portion, and a cap configured to include a plurality of passages.

Abstract: A relief valve for use in coupling to a vessel is disclosed. The valve includes a valve body having an inlet passage connected to a valve inlet, an outlet passage connected to a valve outlet, and an internal chamber. A valve seat is engageable with the inlet passage to close the valve inlet. A poppet is coupled to the valve seat, and a spring in the internal chamber is coupled to the poppet, the spring having a predetermined spring force. A vent passage in the valve body has a first end connected to the internal chamber and a second end connected to the outlet passage to permit release of pressure from the internal chamber through the valve outlet. The vent passage is formed at an oblique angle to both the inlet passage and the outlet passage.

Abstract: An embodiment includes a rapid-connect coupler including a coupler body configured to convey a fluid; a coupling head at a first end of and communicating with the coupler body, the coupling head configured to transition between a coupled configuration and a de-coupled configuration. The coupler may further include a stop apparatus configured to allow the coupling head to transition from the de-coupled configuration to the coupled configuration without obstruction, and the stop apparatus may be configured to provide a hard-stop as the coupling head transitions from the coupled configuration to the de-coupled configuration.

Abstract: A rapid-connect gas coupler is shown and described herein. In an embodiment, the rapid-connect gas coupler includes a spring-loaded probe within a probe cavity, which is defined by a housing and one or more latch segment. The probe can engage with a gas connector, which causes the latch segment to engage and couple with the gas connector.
