Thrust regulator having turbulence generating means for thrust control

Thrust control means in combination with a pressurized container from the interior of which product is to be expelled along a flowpath extending through a discharge valve, said thrust control means enable maintaining the amount of product being expelled from the container per unit of time at least substantially constant during the entire emptying time of said container, notwithstanding the reduction of internal pressure occuring during the progressive emptying of the container,

• said thrust control means comprising:
• (a) a casing,
• (b) a discharge channel in said casing, having a channel axis and a first end connected to said discharge valve and a second end;
• (c) a chamber connected to said second end;
• (d) a spray nozzle connected to said chamber;
• (e) a core in said chamber having radiating channels tangential to and adjacent said second end;
• (f) said chamber having supply channels tangential to said radiating channels and adjacent said radiating channels at one end and adjacent said spray nozzle at the other end;
• (g) a weighted pressure spring located in the interior of said discharge channel;
• (h) a differential piston having a first end and a mid portion engaging said pressure spring and a second larger end disposed closer to said discharge valve than is said first end;
• (i) said discharge channel having an inner wall which narrows continuously from said first end to said second end in a stepped configuration permitting space between said differential piston and said inner wall upon compression of said spring to a first end position when the discharge valve is opened, where an opening in said second end decreases to a minimum;
• and
• (j) said spring having a given weighted compressive strength for expanding proportionally to a pressure drop due to the discharge of said product from said container and shifts said piston so that said opening of said discharge channel increases gradually until said piston has reached a second end position when a given minimum pressure has been reached in said container.
