A probe for a closed transfer system, the probe including a probe body and a probe tip. The probe body defines an inlet, an outlet, and a plurality of channels. The outlet is in fluid communication with the inlet via at least one of the plurality of channels. The probe tip is located at a top end of the probe body and defines a first passageway. The first passageway is in fluid communication with at least one of the plurality of channels. The probe body is configured to be slidably moveable within a coupler body between a first position where the probe tip is received within the coupler body and a second position where the probe tip extends at least partially away from the coupler body to open a fluid flow path through the coupler body.

A probe assembly for a closed transfer system is provided. The probe assembly includes a base having an internal wall, a probe defining a hollow air channel, and a valve configured to selectively allow air into the hollow air channel. The internal wall partially defines and fluidly separates a liquid chamber and an air chamber. The probe is coupled to the base such that the hollow air channel is in fluid communication with the air chamber. The valve is positioned proximate to the air chamber. The liquid chamber is configured to deliver rinse water from a water source.

Systems and methods are disclosed to mix a base ingredient, such as water, with an additive, such as a cleaning concentrate. A dispensing system of the disclosure can include a container filling apparatus. The container filling apparatus can include one or more source containers that contain an additive to be mixed with water or other base ingredient. The container filling apparatus can include a vacuum manifold and a Venturi body assembly (VBA). The additive can be flowed through the vacuum manifold and into the VBA. In the VBA, the additive can be mixed with water or other base ingredient, and output to a receiving container. As the additive is flowed through the vacuum manifold, vacuum pressure in the pressure manifold can be measured by a pressure sensor. A controller can input pressure data from the pressure sensor over the course of a dispense event. Over the course of a dispense event, flow of additive can be varied or modulated based on the pressure data. The flow of additive can be provided, as controlled by the controller, in a sequence of pulses. The length of a pulse, in a dispense event, can be adjusted based on observed pressure data in prior pulses.

A system for filling a tank for a firefighting helicopter with water without ground personnel, comprising a pilot controlled valve assembly to selectively permit water to flow into the refill tank upon the receipt of a communication transmitted by a communication device within the helicopter. The pilot controlled valve assembly can include a supply valve configured to move between at least a closed state and an open state, a controller configured to control the supply valve, and a receiver configured to send a signal to a controller to cause the controller to at least open the supply valve upon receipt by the receiver of a communication meeting one or more predetermined criteria. The water tank can be filled from a water source, including a municipal water source, when the supply valve is open to provide a more efficient, semi-autonomous refill tank system greatly improves costly and time-consuming manually refill systems.

The invention relates to a device for pressure testing, evacuation, and/or filling of a non-vacuum-resistant or non-pressure-resistant assembly by means of vacuum pressure filling or vacuum volume filling, the device comprising a vacuum chamber for accommodating the assembly to be filled and an adapter for filling the assembly to be filled. The problem of the invention is that of providing a respective device which has a compact design with small volumes to enable short evacuation and ventilation times. At the same time, consumption of auxiliary gas is to be kept to a minimum and good handling for an automation system is to be achieved. The problem is solved by releasably assembling the vacuum chamber of the device from a first and a second housing component, specific designs being proposed for these components.

A fluid transfer system, including a liquid container to store a liquid therein, a first valve that facilitates movement of air therethrough, a second valve connected to the first valve and the liquid container to receive at least one of the liquid and the air therethrough, an air dispenser unit connected to the first valve and dispenses the air toward the first valve, and a vacuum generator connected to the first valve and the second valve, the vacuum generator to vacuum the air through the second valve, such that at least one of the liquid and the air moves through the second valve for extraction.

A system for vacuum filling a cooling assembly is provided. The system comprising a manifold comprising a first aperture, a second aperture, and a third aperture. Further, an eductor fluidly coupled to the first aperture, a first valve fluidly coupled between the eductor and the first aperture, and an expansion reservoir sealingly coupled to the second aperture. An end unit is fluidly coupled to the third aperture, the end unit comprising a conduit fluidly coupled with the third aperture, a second valve fluidly coupled to the conduit, a cap for sealingly coupling with a supply volume, and a pipe coupled to the cap and fluidly coupled with the conduit, the pipe sealingly coupled to the cap and extending outwardly from the cap.
