Title: Improvements in and relating to central liquid distribution
IPC: F16N7/38
Filed: 1929-08-02
Abstract: 316,681. Bijur, J. Aug. 2, 1928, [Convention date]. Suction pipes for pumps; regulating pumps.-Lubricant or other liquid is intermittently fed into a distributing system from a source delivering by continuous slow feed to a collecting-chamber until a predetermined level is reached, when the accumulated liquid is quickly discharged therefrom by a siphon to a pump which forces it into the distributing system. As applied to a lubricating system for a motor-vehicle chassis, lubricant flows from a reservoir R, Fig. 4 through a filter 70 into a cup 71, whence it passes through a port 74 into a passage 66 communicating with a pipe 77. The entry to the passage 66 is controlled by a valve 64 at the lower end of a plunger 65, the upper end of which carries, a soft iron sleeve 67 extending into a solenoid 68 connected in series with the engine ignition switch, so that the valve is maintained open only when the engine is running. The pipe 77 leads, through a felt strainer plug 79, into a chamber U, whence the lubricant flows through an aperture 87 into a collecting chamber C provided with an air vent v. The aperture 87 is controlled by a tapered pin 86 carried by a bellows 82 containing an expansible fluid A spring 89 tends to collapse the bellows, so that the flow through the aperture 87 is rendered independent of the viscosity of the lubricant. A siphon 91 aranged in the chamber C and provided with a siphon-breaking pipe 94 discharges the lubricant from the chamber, when it has accumulated therein to a predetermined level, through a pipe 97 to the inlet chamber 95 of a pump 96 which, as shown, is of the gear type provided with a valve-controlled by-pass 103 and with a spring- pressed delivery valve 108. The pump, which is driven continuously from the generator shaft or other part of the engine or from the speedometer drive, delivers the lubricant to the distributing piping p. A vent pipe 104 extends from the chamber 95 to above the highest level of lubricant in the reservoir R. In the construction shown in Fig. 6, lubricant flowing from the reservoir R through a filter 220 into a cup 221 is raised by a screw 224 to a chamber 223 in which a constant level is maintained by an overflow 228 to the reservoir. Lubricant drips from the chamber 223 through a restriction plug 229 into a chamber 230 from which it is discharged, when it has accumulated to a predetermined level,. by a siphon 231 into a chamber 232 from which is passes to the gear pump 236 through a passage 237. The chambers 230, 232 are vented through a tube 233. The screw 224, which drives the pump 236, is driven through gearing by a pulley 239 driven continuously by the machine to be lubricated. Specification 237,958, [Class 12 (iii), Lubricators &c.], is referred to.
