摘要： A flush toilet includes a toilet main body and a tank device. The tank device includes a water supply unit a storage tank, a pump, and a suction pipe. The water supply unit is configured to supply the flush water the storage tank while the pump is being driven. The storage tank includes a large tank section that includes a lowest bottom surface of the storage tank and that is a large-capacity side, and a small tank section that is a small-capacity side. The storage tank main body includes a water supply port on an upper surface of the storage tank. The water supply unit is configured to supply the flush water to the storage tank through the water supply port. The water supply port of the storage tank and an upstream-end opening of the suction pipe are both provided on a large tank section side.

摘要： A manual lubrication system for a manual toilet flush pump on a manual toilet of the type used in boats and RV's. The lubrication system comprises a lubricant reservoir affixed in parallel to the housing of the manual toilet flush pump laterally opposite the toilet, with a movable lubricant pump head located below the operating handle of the manual toilet flush pump and having an operating axis generally parallel to the that of the manual toilet flush pump's operating handle. A positive manual shutoff normally keeps the lubricant reservoir isolated from the normal in-flow of water to and through the manual toilet flush pump except when lubricant is being manually added during a maintenance procedure.
