Definitions
- the present invention relates to an arrangement introduced in a hand-held liquid pump system (1) coupled to a portable tank (2) which permits both vacuum formation and pressurization within the tank; that is, it makes it possible, respectively, to suck liquids and expel them under certain pressure to the point of spraying some types of liquids.
- the system is designed to operate with the most diverse liquid substances, such as agrochemicals, vegetable oils, diesel, kerosene, alcohol, cleaning products, among others. It can be useful in many fields of work, such as mechanical workshops, warehouses and agricultural warehouses, highways (in the containment of liquid leaks in case of car accidents), cleaning of environments, industries, etc.
- the directional valve has a locking system (10) that remains activated when the tank is in the discharge function (positive pressure); To deactivate it it is first necessary to tighten the directional valve until it touches the body of this lock, thus releasing the system pressure and, only after it is possible to lift the lock and change the function (for suction) by fully tightening the directional valve.
- Examples of devices with these characteristics include patent documents PI9002004, PI9200623, U8500559-2, CN202482052, CN103244420 and CN202165232. In such cases, simultaneous suction begins to discharge liquid dg into the top of the cylinder through another opening.
- the suction unit is made up of a pressurization / pumping system and a tank. enables the retention of negative pressure before starting liquid suction, as for example, US patents 6,112,759; US 6,474,443.
- the entire air-conducting as well as function change system is designed in a simple way (function change is performed at the touch / push of a button) and is compact and interconnected inside. of the lower end of a pressurization cylinder.
- the present improvement aims to provide a simpler operating solution with a more compact structural design, in light of current developments in the state of the art, for a liquid suction and discharge system.
- this model seeks to provide easy use for the most lay user, making the most of the pressurization tank - as the entire pumping set is above the tank - with a comfortable height for movement of the pressurization cylinder and also due to Its more compact structure reduces problems / damage as seen on current equipment on the market, resulting in increased durability and operating performance in various work environments.
- Figure 1 illustrates a perspective view of the complete system.
- Figure 2 illustrates a sectional front view of the region of the equipment responsible for switching and activating suction and discharge functions.
- Figure 3 illustrates the operation of the function switching system (suction / discharge).
- A Suction function.
- B Discharge function.
- Figure 4 illustrates a front view of the pressurization cylinder assembly associated with the function (suction / discharge) switch apparatus.
- Figure 1 the hand pump for suction and discharge of liquids is basically comprised of two sets.
- the first set refers to the plastic cylinder (3) obtained by the injection process, which houses the piston (11), piston (12) and the entire function switching apparatus as shown in figure 2.
- the packing tank obtained by the blow molding process, has the function of packing liquids and the whole pressurization and suction set a handle at the lower end to facilitate the use of the equipment (13).
