Abstract

1. Grúa de juguete de accionamiento neumático, que comprende un suministro de aire que expulsa y aspira el aire alternamente, un cuerpo de grúa que eleva una pluma de grúa que está soportada con susceptibilidad de rotación con su extremo de base como centro contando con la operación de dilatación y contracción de un fuelle, y un dispositivo valvular que incluye un recorrido de aire que conecta dicho suministro de aire al fuelle de dicho cuerpo de grúa, caracterizada porque dicho dispositivo valvular consiste en una válvula accionada por presión positiva que está dispuesta en dicho recorrido de aire que se abre bajo la presión que se produce cuando se expulsa el aire de dicho suministro de alimentar el aire a dicho fuelle, una válvula accionada por presión negativa que está dispuesta en el recorrido de aire entre dicha válvula accionada por presión positiva y dicho suministro de aire y que se abre por la presión que se produce cuando se aspira el aire en dicho suministro de aire, a fin de comunicar dicho recorrido de aire con el aire libre y una válvula de purga que vacía el aire que llena dicho fuelle de modo que se permite la contracción de dicho fuelle. 2. Grúa de jueguete de accionamiento neumático.
