Abstract

bomba de membrana com uma válvula de extensão de vazamento controlada por inércia. a presente invenção refere-se a uma bomba de membrana, com uma câmara de transporte (9) separada de uma câmara hifráulica (8) através de uma membarana (1), sendo que, a câmara de transporte (9) está ligada respectivamente, com uma conexão de aspiração e com uma conexão de pressão,e a câmara hidráulica (8) que pode ser preenchida com um líquido de trabalho pode ser admtida com uma pressão de líquido de trabalho pulante, sendo que, a câmara hidráulica (8) está ligada com uma reserva do líquido de trabalho (15) através de uma válvula de extensão de vazamento (6), sendo que, a válvula de extensão de vazamento (6) apresenta um corpo de fechamento que pode ser movimentado de um lado para o outro, entre uma posição de fechamento, na qual a passagem da válvula está fechada, e uma posição de abertura, na qual a pássagem da válvula está aberta, o qual é mantido na posição de fechamento com auxílio de um elemento de pressão, sendo que, o elemento de pressão é projetado de tal modo que quando a pressão na câmara hidráulica (8) é menor que uma pressão de ajuste p~ l~ o corpo de fechamento (16) se movimenta na direção da posição de abertura. a fim de preparar uma bomba de membrana com uma válvula de extensão de vazamento, de tal modo que, as desvantagens do estado da técnica sejam reduzidas, ou até mesmo superadas, de acordo com a invenção é sugerido que, a massa do corpo de fechamento (16) seja tão grande que, o corpo de fechamento (16) se movimenta durante uma queda de pressão para 0 mpa (0 bar), que não dura mais que 1 milissegundo, em virtude de um choque de pressão na câmara hidráulica (8) em torno de não mais que 0,2 mm na direção da posição de abertura.membrane pump with an inertia controlled leak extension valve. The present invention relates to a membrane pump having a transport chamber (9) separated from a hydraulic chamber (8) by means of a membarana (1), wherein the transport chamber (9) is connected respectively. with a suction fitting and a pressure fitting, and the hydraulic chamber (8) that can be filled with a working liquid can be admitted with a jumping working pressure, whereby the hydraulic chamber (8) is connected with a working fluid reserve (15) via a leakage extension valve (6), and the leakage extension valve (6) has a closing body that can be moved from side to side , between a closing position in which the valve passage is closed and an opening position in which the valve bird is open which is held in the closed position with the aid of a pressure element, whereby, the pressure element it is designed such that when the pressure in the hydraulic chamber (8) is smaller than a set pressure p ~ l ~ closing body (16) moves toward the open position. In order to prepare a membrane pump with a leakage extension valve such that the disadvantages of the state of the art are reduced, or even overcome, according to the invention it is suggested that the mass of the closing body (16) is so large that the closure body (16) moves during a pressure drop to 0 mpa (0 bar), which lasts no longer than 1 millisecond, due to a pressure shock in the hydraulic chamber (8). ) about no more than 0.2 mm in the direction of the open position.
