Abstract: A leak stop assembly for an automatic shut-off fluid nozzle having a fluid flow path and a check valve with a through bore in the flow path. The assembly includes a bleeder seat that houses a length of the flow path proximate the check valve, a rubber plug, and a rigid cross-brace attached to the bleeder seat and holding the plug. Fluid flows around the check valve when open. The cross-brace positions the plug relative to the check valve through bore such that the plug seals against the check valve through bore when the check valve is closed.

Abstract: An automatic shut-off fluid nozzle having a primary fluid path, a vacuum-actuated fluid shut-off assembly in the fluid path, said shut-off shutting off flow through the fluid path when the pressure chamber is subjected to a predetermined vacuum. The nozzle having a venturi port in said fluid path and connected to a vacuum channel, and a vacuum vent extending away from the vacuum channel, said vacuum vent communicating with a low vacuum environment. The nozzle further having a segregated fluid channel in the primary fluid path, the venturi port communicating with said segregated fluid channel, such that the flow of fluid past the venturi port creates a venturi vacuum in the vacuum channel. The vacuum exhausts the vacuum through the vent port when the vent port is in an open condition, and creates a vacuum in the vacuum-actuated fluid shut-off assembly when said vent port is in a closed condition.
