Fluid control assemblies and flow path inserts

A fluid control assembly comprising:

• a body, the body defining a fluid inlet passage, a fluid outlet passage, and a valve inlet orifice;
• a pressure regulator coupled with the body and at least partially defining a regulator chamber, the pressure regulator operably regulating a pressure of a fluid flowing through the body from the fluid inlet passage to the fluid outlet passage;
• and
• a flow path insert positioned within, and engaged with, the body, the flow path insert comprising an ignition-resistant material and defining an inlet passage and an outlet passage in fluid communication with the inlet passage, the inlet passage defining a first axis, the outlet passage defining a second axis transverse to the first axis;
• wherein
• the inlet passage defined by the flow path insert is in at least selective fluid communication with the fluid inlet passage;
• and
• the flow path insert cooperates with at least the body to define an annular passage in fluid communication with the outlet passage defined by the flow path insert, and with the valve inlet orifice, the regulator inlet orifice being in at least intermittent fluid communication with the regulator chamber.

A fluid control assembly comprising:

• a body, the body defining a fluid inlet passage, a fluid outlet passage, and a valve inlet orifice;
• a pressure regulator coupled with the body and at least partially defining a regulator chamber, the pressure regulator being downstream of the fluid inlet passage and upstream of the fluid outlet passage;
• and
• a plurality of flow path inserts, each of the flow path inserts being positioned within, and engaged with, the body;
• wherein
• for each of the flow path inserts, the flow path insert comprises an ignition-resistant material and defines an inlet passage and an outlet passage in fluid communication with the inlet passage, the inlet passage defining a first axis, the outlet passage defining a second axis transverse to the first axis;
• and
• for each of the flow path inserts, the flow path insert cooperates with at least the body to define an annular passage in fluid communication with the outlet passage.

A fluid control assembly comprising:

• a pressure regulator coupled with the body and at least partially defining a regulator chamber, the regulator chamber being in at least intermittent fluid communication with the valve inlet orifice;
• and
• a multi-function valve coupled with the body, the multi-function valve comprising:
• a knob, the knob being rotatable relative to the body;
• an orifice plate coupled with the knob, the orifice plate defining a plurality of circumferentially spaced orifices;
• a valve seat;
• a valve structure translatable relative to the valve seat between a closed position and an open position;
• and
• a biasing member, the biasing member biasing the valve structure toward the closed position;
• wherein
• the valve structure is translatable between the closed position and the open position in response to rotation of the knob, such that the fluid inlet passage is in selective fluid communication with the valve inlet orifice;
• and
• the orifice plate is rotatable with the knob, such that each of the orifices is in selective fluid communication with each of the regulator chamber and the fluid outlet passage, in response to rotation of the knob.

A flow path insert for a fluid control assembly, the flow path insert comprising:

• a first portion and a second portion integral with the first portion, the first portion comprising a first peripheral surface, the second portion comprising a second peripheral surface;
• wherein
• the first peripheral surface has a first diameter and the second peripheral surface has a second diameter, the first diameter being greater than the second diameter;
• the first portion and the second portion cooperate to define a first passage and a second passage in fluid communication with the first passage, the second passage extending through the second peripheral surface;
• the first passage defines a first axis and the second passage defines a second axis, the second axis being transverse to the first axis;
• and
• when the flow path insert is positioned within a body of a fluid control assembly, the first peripheral surface is in contacting engagement with the body and the second peripheral surface is spaced from the body, at least the second portion of the flow path insert and the body cooperating to define an annular passage in fluid communication with the second passage.
