Combination relief valve and injection fitting

A bleed valve and injection fitting adapted for use in an access port of a fluid chamber, the bleed valve and injection fitting comprising:

• a body having a first end and a second end, the first end being formed with a injection fitting and the second end including a sealing surface selectively sealable to an inner surface of the access port;
• a bi-directional passageway extending through the body from the first end part of the way towards the second end;
• a one-way passageway extending from the bi-directional passageway to the second end;
• and
• a bypass passageway separate from the one-way passageway, the bypass passageway extending from the sealing surface to the bi-directional passageway.

A fluid chamber for holding a pressurized fluid, the fluid chamber comprising:

• a chamber defining an inner cavity and having an access port for accessing the inner cavity, the access port having a first surface and a second surface;
• and
• a valve for regulating the flow of fluid through the access port, the valve including:
• a body having a first end and a second end, downstream of the first end of the body;
• a sealing interface between the body and the first surface;
• a selective sealing interface between the body and the second surface;
• a first passageway extending through the body from the first end to the second end;
• an injection fitting formed at the first end of the body in fluid communication with the first passageway;
• a one-way valve assembly positioned within the first passageway, the one-way valve assembly being arranged to permit a flow of fluid therethrough in a downstream direction and prevent the flow of fluid therethrough in an upstream direction;
• a second passageway extending from the selective sealing interface separate from the first passageway;
• and
• a connecting passageway connecting the second passageway with the first passageway upstream of the one-way valve assembly.
