Abstract
1461745 Combined liquid and gas pumps BEATRICE FOODS CO 5 Aug 1975 [9 Sept 1974] 32710/75 Heading F1A A pump 10 for supplying a mixture of liquid confection and air to a freezing chamber (34), e.g. for producing “soft” ice cream, comprises a cylinder 40 closed at one end by a plug 50 and containing a piston 60 reciprocable therein, the pumping chamber 55 defined between the plug 50 and the piston being supplied with air through the piston via passage 66-68 including a restriction 76 and with liquid through a passage 92, 93 in the plug. On the delivery stroke the mixture is delivered through a passage 86, 88, (87) and past a non-return delivery valve 97 to an outlet 42. The valve 97 and inlet valves 72, 96 controlling flow through the passages 66-68 and 92, 93, respectively, are identical and comprise radially extendable elastomeric rings. A crank pin 63 having a balled end 64 received in a socket 61 in the piston 60 is driven by a motor 14 through a gear-box 12 to cause the piston to reciprocate. Pins 46, 51 are removed to allow the cylinder to be disengaged from the crank pin 63 and the plug 50 from the cylinder to facilitate cleaning. The cylinder may be of stainless steel, and the plug 50 and piston 60 of poly acetol.
