Patent number: 4028012Abstract: A novel sealing arrangement for mounting a combination pump-motor assembly in sealed relationship to the bottom opening of a dishwasher tub, whereby a fluid-tight seal is insured, notwithstanding thermal expansion and contraction of the tub bottom. The seal is effected between a circumferential downwardly directed bead, of a flexible shroud that covers the assembly, and an upwardly facing grooved lip which defines the opening in the tub bottom whereby the weight of the wash fluid in the tub tends to enhance the sealing action.Type: GrantFiled: June 2, 1975Date of Patent: June 7, 1977Assignee: General Electric CompanyInventor: Donald S.
