A hose end regulator for regulating pressure in fluid comprising: a main body having a fluid inlet and a fluid outlet; a poppet moving between an open position to permit a fluid to flow through the fluid outlet and a closed position to militate against the fluid flowing through the fluid outlet; a primary spring (22, 22') permitting the poppet to move between the open position and the closed position, the primary spring (22, 22') urging the poppet to the open position; and a flow maximizer (20, 20') minimizing movement of the primary spring (22, 22') until a predetermined fluid pressure is reached within the main body, and wherein the flow maximizer (20, 20') is received in the primary spring (22, 22'), and wherein the flow maximizer (20, 20') includes a body (1, 1') and an actuator (5, 5') received at least partially within the body (1, 1'), and wherein a return spring (2, 2') is disposed within the body (1, 1') and extends between a first end of the body (1, 1') and the actuator (5, 5'), and characterized in that the actuator (5, 5') cooperates with release balls disposed within catches (4a, 4a') formed on an inner surface of the body (1, 1') to regulate movement of the actuator (5, 5'), the return spring (2, 2'), and the primary spring (22, 22'), and wherein at least four release balls extend through the actuator (5, 5'), and wherein a release pin assembly cooperates with the release balls to regulate movement of the actuator (5, 5'), the return spring (2, 2'), and the primary spring (22, 22'), wherein the release pin assembly includes a release pin configured to engage the release balls, an adjuster spring cooperating with the release pin to regulate movement of the actuator (5, 5'), and an adjustment screw adjusting a spring force of the adjuster spring. a main body having a fluid inlet and a fluid outlet; a poppet moving between an open position to permit a fluid to flow through the fluid outlet and a closed position to militate against the fluid flowing through the fluid outlet; a primary spring (22, 22') permitting the poppet to move between the open position and the closed position, the primary spring (22, 22') urging the poppet to the open position; and a flow maximizer (20, 20') minimizing movement of the primary spring (22, 22') until a predetermined fluid pressure is reached within the main body, and wherein the flow maximizer (20, 20') is received in the primary spring (22, 22'), and wherein the flow maximizer (20, 20') includes a body (1, 1') and an actuator (5, 5') received at least partially within the body (1, 1'), and wherein a return spring (2, 2') is disposed within the body (1, 1') and extends between a first end of the body (1, 1') and the actuator (5, 5'), and characterized in that the actuator (5, 5') cooperates with release balls disposed within catches (4a, 4a') formed on an inner surface of the body (1, 1') to regulate movement of the actuator (5, 5'), the return spring (2, 2'), and the primary spring (22, 22'), and wherein at least four release balls extend through the actuator (5, 5'), and wherein a release pin assembly cooperates with the release balls to regulate movement of the actuator (5, 5'), the return spring (2, 2'), and the primary spring (22, 22'), wherein the release pin assembly includes a release pin configured to engage the release balls, an adjuster spring cooperating with the release pin to regulate movement of the actuator (5, 5'), and an adjustment screw adjusting a spring force of the adjuster spring.
