Abstract

850,518. Gear pumps. CARVER, P. W., and KONTAK MANUFACTURING CO. Ltd. May 29, 1957 [May 29, 1956 (2)], Nos. 16650/56 and 16652/56. Class 110 (2). [Also in Group XXVIII] A gear pump 110 having inlet and outlet passages 12, 11 circulates liquid to actuate a diaphragm pump (see - Group XXVIII). The pump is driven by an electric motor 111 and a reservoir chamber 117 is provided above the pump which is partially filled with liquid to a level 118 providing an air space 119 above it vented to the atmosphere. The pump delivers a greater volume of liquid than that required to actuate the diaphragm pump and the excess delivery is by-passed through a valve 120 to the reservoir from which liquid is drawn past a valve 121 to the suction side of the pump. Air bubbles in the circulating circuit flow through the inlet 12 and pass upwardsthrough an orifice 126 to a float chamber 125 containing a float valve 124 which controls an orifice 122 communicating with the reservoir chamber. As the air collects in the float chamber the valve 124 falls until the orifice 122 is opened when the air passes into the reservoir chamber and to the atmosphere and liquid flows from the reservoir into the float chamber until the valve 124 is raised to close the orifice 122.
