Abstract
Un dispositivo miniaturizado para la generación de alta presión en un fluido plantea altos requisitos al procedimiento de fabricación. El dispositivo según la invención consta de un piston hueco, que está dispuesto desplazable en un cilindro, asi como de un cuerpo de válvula, que está dispuesto guiado por el pistón hueco y desplazable axialmente respecto al pistón hueco. El cuerpo de válvula está dispuesto en un extremo del pistón hueco, dentro o inmediatamente delante del extremo del pistón hueco. El dispositivo se emplea en un pulverizador de alte presión de funcionamiento mecánico. Este consta de una envoltura de dos piezas, que contiene una envuelta de bomba con tobera, un mecanismo de tensado con bloqueo, una envuelta del resorte con resorte, un dispositivo de almacenamiento sin presión para el fluido y un contador mecánico integrado en la envuelta del resorte. La válvula trabaja sin fuerza auxiliar, cierra muy rapidamente y es estanca contra alta presión. El pulverizador esseguro y fácil de manejar, y respetuoso con el medio ambiente. La dosificación del fluido es muy precisa. El pulverizador sirve por ejemplo para la generación excenta de gas propulsor de un aerosol inhalable a partir de un medicamento líquido a por ejemplo 320 bar.A miniaturized device for generating high pressure in a fluid places high requirements on the manufacturing procedure. The device according to the invention consists of a hollow piston, which is displaceable in a cylinder, as well as of a valve body, which is arranged guided by the hollow piston and axially displaceable with respect to the hollow piston. The valve body is disposed at one end of the hollow piston, within or immediately in front of the end of the hollow piston. The device is used in a mechanically operated high pressure sprayer. This consists of a two-piece casing, which contains a pump casing with a nozzle, a locking tensioning mechanism, a spring casing with spring, a pressureless storage device for the fluid, and a mechanical meter integrated in the casing of the spring. The valve works without auxiliary force, closes very quickly and is tight against high pressure. The sprayer is safe and easy to operate, and environmentally friendly. The dosing of the fluid is very precise. The sprayer serves, for example, for the generation of propellant gas from an inhalable aerosol from a liquid medicine at, for example, 320 bar.
