Abstract

Un mécanisme de chevalet de pompage est présenté comprenant un chevalet de pompage, une tige couplée au balancier d'une pompe de puits et un frein à friction fixé à la tige. Le frein à friction permet la rotation de la tige dans une première direction relativement à un cadre de référence, mais bloque par friction la tige lors de l'inversion de la rotation de la tige pour empêcher l'effet de recul de la tige. Dans certaines réalisations, le mécanisme de chevet de pompage comprend également un rotateur de tige couplé à la tige qui, en fonction, entraîne la tige à pivoter dans la première direction relativement au cadre de référence fixé.
