An apparatus for compressing a predetermined volume of air without the use of an independent motor-driven air compressor and for delivering said compressed air under pressure to the evacuation chamber of a pneumatic assisted water flush toilet bowl to discharge waste products from the evacuation chamber, comprising: (a) a fluid-tight housing having walls defining a hollow interior; (b) at least one piston reciprocable within said housing and constituting a displaceable wall defining with said housing walls a pair of chambers variable in volume in response to displacement of said piston, one of said chambers of said pair containing air at a predetermined pressure; (c) means controlling admission of water under pressure to the other chamber of the pair to effect displacement of the piston to reduce the volume of the first mentioned chamber of the pair to pressurize the air therewithin above said predetermined pressure; and (d) means controlling delivery to said evacuation chamber of pressurized air from said other chamber of the pair to thereby effect discharge of waste products from said evacuation chamber.
