ABSTRACT:
An air bedding system with a diapghagm pump built into it. The diaphragm pump is comprised of a shaft, means for rotating the shaft at a speed of less than 3,300 revolutions per minute, a first connecting rod connected to a first diaphragm and operatively connected to the shaft, a second connecting rod connected to a second diaphragm and operatively connected to the shaft, and means for converting rotary motion of the shaft into reciprocating linear motion of both the first connecting rod and the second connecting rod such that, as the first connecting rod is moved in a first direction at a first rate of travel, the second connecting rod is simultaneously moved in a second linear direction at a second rate of travel, which is equal to said first rate of travel, and wherein the second linear direction is the opposite of the first linear direction.
