Embodiments described herein are generally directed to a venturi valve. The venture valve includes an inlet; an outlet opposite of the inlet; a passage, a primary orifice, and an insert. The passage is positioned between the inlet and the outlet and fluidly coupling the inlet to the outlet. The primary orifice is positioned between the inlet and the outlet and in fluid communication with the passage such that the primary orifice permits fluid to enter the passage. The insert is positioned between the inlet and the outlet, the insert configured to enclose at least a portion of the passage.

A docking fixture for removal of a valve core from a valve fitting of a pressurized system includes a main body defining a hollow main channel that receives a gripping probe to remove the core of a charging valve that is part of a pressurized HVAC system. The docking fixture has a proximal end that can be connected to the HVAC fitting that houses the valve core that is to be removed and replaced. The docking fixture has a side port integrated with a slide valve that can be closed to isolate and protect a sensitive vacuum pressure gauge that might be connected to the free end the fixture's side port. The slide valve includes a sleeve and a tactile feedback mechanism that is configured to provide tactile sensation when the sleeve is positioned in one of the open position and the closed position of the slide valve.

A receiver for a heating, air conditioning, and refrigeration system includes a tube extending along a tube axis from a first receiver end to a second receiver end opposite the first receiver end, and a single receiver port. The receiver port is configured as both a receiver inlet and a receiver outlet. A heating, air conditioning, and refrigeration system includes a compressor configured to compress a refrigerant flow, a refrigerant pathway configured to convey the refrigerant flow through the heating, air conditioning, and refrigeration system, and a receiver fluidly connected to the refrigerant pathway. The receiver includes a tube extending along a tube axis from a first receiver end to a second receiver end opposite the first receiver end, and a single receiver port. The receiver port is configured as both a receiver inlet and a receiver outlet, and is connected to the refrigerant pathway via the single receiver port.

An integrated valve includes a connecting member including a first valve element and a second valve element. The first valve element is disposed in a pressure reducing chamber of a body of the integrated valve and forms a pressure reducing valve that reduces the pressure of the refrigerant discharged from a compressor. The second valve element is disposed in an on-off valve chamber of the body and forms an on-off valve for adjusting a flow rate of the refrigerant flowing into an intermediate-pressure port of the compressor. The on-off valve is in a fully opened state when the pressure reducing valve is in a throttling state, the on-off valve is in an opened state when the pressure reducing valve is in an opened state, and the on-off valve is in a closed state when the pressure reducing valve is in a fully opened state.
