Valves and valve assemblies

A valve assembly comprising:

• a housing comprising:
• an inlet port;
• an outlet port;
• and
• an assembly portion;
• wherein the inlet port, the outlet port, and the assembly portion jointly form a first single integral and continuous piece;
• and
• a poppet-carrying portion configured to engage with the housing, the poppet-carrying portion comprising:
• a poppet head configured to move within the housing;
• a closure having a mating portion configured to engage with the assembly portion of the housing;
• a convolution extending between the poppet head and the closure, the convolution configured to provide compliance such that the poppet head moves relative to the closure;
• and
• a stopping portion extending from the closure toward the poppet head and spaced apart from the poppet head;
• wherein the poppet head, the closure, the convolution, and the stopping portion jointly form a second single integral and continuous piece.

A valve comprising:

• an inlet located at an inlet end of the valve;
• an outlet located at an outlet end of the valve;
• a valve wall extending from the inlet end to the outlet end and enclosing a space between the inlet and the outlet to form a valve cavity, the valve cavity configured to receive fluid that enters through the inlet;
• and
• a plurality of compliance beams extending from the outlet end into the valve cavity and spaced apart to form a flow path to the outlet, the plurality of compliance beams comprising:
• a first end located spaced apart from the inlet and forming an inlet cavity of the flow path;
• a second end located at the outlet and forming an outlet cavity of the flow path;
• and
• a valve neck connecting the first end and the second end to form a throat section of the flow path, the throat section having a length and a width;
• wherein fluid is configured to pass through the flow path by converging at the inlet cavity, passing through the throat section along the length of the throat section, and diverging out of the throat section at the outlet cavity;
• and
• wherein an increase in velocity of the fluid passing through the flow path reduces the width of the throat section.
