A toilet having a seat section that includes a bowl with a bottom discharge opening. The toilet also includes a source of flush water for rinsing the bowl and removing waste through the discharge opening into a waste storage tank. A pump provides the flush water through a nozzle which directs the flush water into the bowl. A check valve is associated with discharge nozzle to prevent flush water from inadvertently leaking into the bowl. The check valve is capable of being used with either a manually actuated pump or a power assisted pump and reduces the force required by the pump to maintain the valve open than to initially open it.

A vent for a removable toilet holding tank includes a valve member that is in communication with both the holding tank interior and the ambient atmosphere and is moved off its valve seat when the pressure within the holding tank exceeds the ambient pressure by an amount sufficient to overcome the force of gravity acting to hold the valve member against its valve seat. The vent further includes a second valve member which is operable to close the vent when the holding tank is removed from the toilet bowl thereby precluding spillage of the tank contents during handling of the tank when separated from the toilet bowl.

Pressure relief vent for a waste holding tank

A mechanism for multiplying rotation. The mechanism includes two armatures of differing lengths which rotate about different centers of rotation. The armatures are coupled together such that a rotation of one armature will produce a multiplied rotation in the other armature. The multiplying mechanism has particular application with a valve assembly of the type used in self-contained sanitary systems of recreational vehicles. The valve assembly includes a seal element having a sealing lip directed toward generally inward and downward of a fill opening a valve blade in the holding tank. The sealing lip terminates in a downwardly and outwardly oriented flange. The valve blade is actuatable through two movements. The first movement moves the valve blade generally vertically into and out of engagement with the seal element. The second movement moves the valve blade generally horizontally to a position out of registry with the fill opening.
