Abstract

138,627. Compagnie pour la Fabrication des Compteurs et MatÚriÚl d'Usines Ó Gaz. Jan. 18, 1919, [Convention date]. Movable-abutment type; compensating for irregularity of flow.-To ensure steady delivery, a Roots' blower is provided with a pair of pistons g, h on one shaft e co-acting with another pair i, k on a parallel shaft f, and the pistons of each pair are arranged at 90 degrees to one another. A partition l is disposed between the pistons g, i and the pistons h, k.
