Abstract

1,001,337. Hydraulic apparatus. RICHIER S.A. July 14, 1964 [July 19, 1963; Oct. 18, 1963], No. 29018/64. Heading F1P. A completely filled reservoir 1, Fig. 1, from which a pump E draws hydromatic fluid through a line 3 for delivery through a line 4, distributing valves 5 and a line 7 to an hydraulic motor D which in turn exhausts to the reservoir through a line 8 is of flexible bellows construction and encloses a hollow filter 11 into which the inlet line 8 opens and the reservoir wall 2 is cooled by air flow thereover. The expansible wall 2 comprises stacked and welded dished annular elements supported by a hollow base-plate 19 forming load and return manifolds 6, 9 and serving to support filter 11 and diffusers 10. The closed upper end cover 13 is spring biased downwardly and is guided by rods 17. In the event of clogging of filter 11 the latter is by-passed through an overload valve 18 whereby unfiltered fluid passes to the pump feed line 3. The motor D drives a concrete mixer A the water supply of which may be used to cool the reservoir wall 2.
