Abstract

385,887. Pumps. EATON, M. M., 18, Brearley Street, Birmingham. July 14, 1932, No. 19901. [Class 102 (i).] In pumps, particularly for delivering water under high pressure to hydraulically actuated appliances having an irregular demand, an auxiliary piston 14 of larger diameter than the pump piston 1 is provided in a relief chamber 13 coaxial with the pump cylinder 2. The relief piston 14 has a collar 16 with intermediate packing 15 which collar is pressed upon by a spring 19 the other end of which abuts upon an adjustable cover 18. The pump plunger is directly connected to a frame 5 carrying rollers 4 which bear against the actuating eccentric 3. On the pressure of the working pump rising to a predetermined limit owing to a falling off in demand, the relief piston is forced back against its spring and the delivery does not pass through the delivery valve 8. In a modification the relief piston bears directly against its spring, the intermediate member 16 being omitted. Specification 385,549, [Group XXVI], is referred to.
