Abstract
Dispositivo de detención automática del giro de un motor hidráulico (1), por ejemplo de un motor de arrastre de la tortea pivotante de una pala, caracterizado porque, sobre las dos canalizaciones de alimentación (9 y 10) del motor, entre este último y el distribuidor principal de mando, va montada, en paralelo con el motor, una electroválvula (48) cuyo orificio de paso bidireccional presenta un estrangulamiento (53), comprendiendo la mencionada electroválvula, por una parte, un mando (38) acoplado al distribuidor principal (7), de forma que la electroválvula se encuentre en su posición cerrada cuando el distribuidor accione el giro normal de motor, pero que se encuentre en su posición abierta (53) al cerrarse el distribuidor principal, por otra parte, un mando (61, 63, 38) en el sentido de cierre, acoplado a un detector (60 de una posición angular determinada (61) del motor con relación a la posición de detención deseada.
