摘要： A sewage pumping system for use in residential sewer systems. The pumping system includes a sump (14), an intake conduit (42), a discharge conduit (44), and a pump (18) for pumping sewage from the sump through the intake and discharge conduits (42,44). The pump (18) is a piston type pump with rolling resilient O-rings (24) received between the piston (22) and the cylinder (20). A pair of check valves (48a,48b) is provided, one in the intake conduit (42) and the other in the discharge conduit (44) to ensure that the flow through the conduits is unidirectional.

摘要： A sewage pumping system for use in residential sewer systems. The pumping system (10) includes a sump (14), a intake conduit (42), a discharge conduit (44), and a pump (18) for pumping sewage from the sump through the intake into discharge conduits. The pump (18) is a piston type pump with rolling resilient O-rings (24) received between the piston (22) and cylinder (20). Four check valves are provided, two of which are located in the intake conduit (48a, 48b) and two of which are located in the discharge conduit (48c, 48d). The check valves in the intake conduit are spaced apart approximately 3 to 4 feet and the check valves and the intake conduit are also spaced apart approximately 3 to 4 feet. The check valves insure that the flow through the conduits is unidirectional and the spacing of the check valves insures that they will not be both wedged in the open position by passage of debris therethrough.

摘要： An apparatus for rerounding flexible deflected pipe and having a housing (10) of slightly smaller outside diameter than the inside diameter of a pipe to be rerounded. The apparatus includes a plurality of bearings (18, 19, 20) in which a crankshaft (14) is journalled. The crankshaft (14) supports an eccentrically mounted weight (36) for generating vibrations in the crankshaft (14) when the crankshaft (14) is rotated. An air motor (40) drives the crankshaft (14). The crankshaft includes a central bore (68) and radial passages (70, 72) for equalizing air pressure across the bearings (18, 19, 20). Flanges (26, 28) are secured in heat conducting relationship with both the bearings (18, 19) and with the housing (10) to conduct heat away from the bearings (18, 19), thereby cooling the bearings (18, 19). One of the flanges (28) includes apertures (34) for conducting air which is expelled from the air motor (40), thereby cooling the flange (28) and the bearings (18, 19).
