Diaphragm for a diaphragm pump

A diaphragm for a diaphragm pump is in the form of a vehicle tire. The vehicular tire has a first mounting face, a second mounting face and a circumferential tread portion positioned between first mounting face and the second mounting face. A first sealing disk is secured to the first mounting face of the tire. A second sealing disk is secured to the second mounting face of the tire. An inlet valve positioned on either the first sealing disk or the second sealing disk. An outlet valve is positioned on either the first sealing disk or the second sealing disk. A diaphragm pump, comprising: a housing; a diaphragm consisting of: a vehicular tire having a first mounting face, a second mounting face and a circumferential tread portion positioned between first mounting face and the second mounting face; a first sealing disk secured to the first mounting face of the tire; a second sealing disk secured to the second mounting face of the tire; an inlet valve positioned on one of the first sealing disk and the second sealing disk; and an outlet valve positioned on one of the first sealing disk and the second sealing disk; the second sealing disk being secured to the housing; a reciprocating member attached to the first sealing disk, the reciprocating member moving the first sealing disk toward and away from the second sealing disk as the reciprocating member reciprocates; and a drive linkage that drives the reciprocating member. According to the present invention there is provided a diaphragm for a diaphragm pump which is in the form of a vehicle tire. The vehicular tire has a first mounting face, a second mounting face and a circumferential tread portion positioned between first mounting face and the second mounting face. A first sealing disk is secured to the first mounting face of the tire. A second sealing disk is secured to the second mounting face of the tire. An inlet valve positioned on either the first sealing disk or the second sealing disk. An outlet valve is positioned on either the first sealing disk or the second sealing disk. A great deal of engineering has gone into vehicular tires to ensure they are not subject to premature failure. These qualities of durability, enable the vehicular tire to function as an extremely robust form of diaphragm for a diaphragm pump. Some vehicular tires function better than others. There are very few diaphragm pumps that are large enough or powerful enough to function with a truck tire. In contrast, a trailer tire or a wheel barrow tire can be made to function with some models of diaphragm pump currently available.
