The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

A plant watering container that includes a container body, a liquid pump system and an extendable and retractable dispensing arm system.

A delivery device (5) for injecting a liquid active ingredient formulation (4) into a plant comprises a vessel assembly (51, 52) having a distal side (512) and a proximal side (523), a delivery outlet (53) connected to the distal side (512) of the vessel assembly (51, 52), a product port (57) connected to the distal side (512) of the vessel assembly (51, 52), a dosing piston (511) movably arranged in the vessel assembly (51, 52) such that a variable product chamber (515; 595) is formed between the dosing piston (511) and the distal side (512) of the vessel assembly (51), a directional valve (54) connected to the proximal side (523) of the vessel assembly (51, 52), a proximal chamber (525) limited by the proximal side (523) of the vessel assembly (51, 52) and reciprocally variable relative to the product chamber (515), and a pressure medium port (541) connected to the directional valve (54). The directional valve (54) is configured to switch between a delivery position in which the proximal chamber (525) of the vessel assembly (51, 52) and the pressure medium port (541) are in fluid connection, and a charging position in which the proximal chamber (525) of the vessel assembly (52) and the pressure medium port (541) are fluid tight towards each other.

A device and method of watering plants using a programmable bucket is described. In one version, the programmable bucket uses a reservoir for water, a pump, at least one minimum pressure valve, a control enclosure, a water level switch, a flow meter, a watering hose, and a cover with an opening adapted to facilitate filling of the reservoir with a funnel and a removable plug. In use, power to the control enclosure is turned on and the reservoir is filled with water, setting the calibrated amount of water. The watering hose is removed from a recycling adaptor, the pump is activated through use of pushbuttons on the control enclosure, water fills the watering hose, once it reaches a minimum pressure valve water exits the hose under pressure, a signal from flow meter changes a volume of water in reservoir.

A modular frame for a backpack sprayer system includes a frame plate having a front surface, a back surface and first and second side edges. A first receiving channel is located along the first side edge and a second receiving channel is located along the second side edge. A support member has a first arm which is received within the first receiving channel and a second arm which is received within the second receiving channel. A stand portion extends at an angle relative to the first and second arms. A mounting member is coupled to the front surface of the frame plate and mounts a tank and a pump unit thereon. The mounting member includes opposing left and right sides, a planar top face and a front face including a concave portion to receive at least a portion of one or both of the tank and the pump unit.

A pumping device for liquids is described which comprises a tank for liquids, from which a feeding pipe of a pump with a solar panel draws. The tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar of the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted. The bag has a lower filling hole or mouth, in which the feeding pipe can be inserted and an overflow hole made in the upper of part of its side wall in position lower than said mouth.

A water spraying system includes an engine, a pump driven by the engine, the pump including a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure, a sprayer fluidly coupled to the pump outlet, the sprayer including a flow restriction valve and a trigger for manipulating the flow restriction valve so that movement of the trigger selectively opens and closes the flow restriction valve, a flow sensor configured to sense a flow of water into the pump, and a controller coupled to the flow sensor. The controller is configured to turn off the engine following a set time period of sensed flow below a threshold flow.

A water spraying system includes an engine, a pump driven by the engine, the pump including a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure, a sprayer fluidly coupled to the pump outlet, the sprayer including a flow restriction valve, a trigger for operating the flow restriction valve, and a wireless transmitter configured to transmit a wireless start signal indicating release of the flow restriction valve, a wireless receiver, and a controller coupled to the wireless receiver, wherein the wireless receiver receives the wireless start signal from the wireless transmitter and in response the controller activates the pump by starting the engine.

A rigid wand receives water under pressure from a pump. A canister of larger diameter than the wand receives the water from the wand with impact on flow disruptive material promoting aeration by turbulence. A large number of peripheral outlet ports allow water to tumble out of the canister through the ports.
