Limit valve for an elastic bladder

A portable watering device for discharging a fluid under pressure, the portable watering device comprising:

• a bladder that is resiliently expandable from a relaxed state to a predetermined expanded state, the bladder when in the relaxed state has a minimum bladder length extending between opposite ends of the bladder;
• a limit valve coupled to the bladder, the limit valve having an open position and a closed position;
• an actuator that is flexible and elongated, the actuator is inside the bladder and extends between the opposite ends of the bladder, the actuator is connected to the limit valve, the actuator has a taut state and a looser state, the actuator is in the taut state when the bladder is in the predetermined expanded state, the actuator is in the looser state when the bladder is in the relaxed state, the limit valve moves between the open position and the closed position in response to the actuator moving between the taut state and the looser state, the actuator has a maximum actuator length when the actuator is in the taut state, the maximum actuator length is greater than the minimum bladder length;
• and
• an anchor disposed within an opening defined by the bladder, the opening is spaced apart from the limit valve, and the actuator engages the anchor.
