Title: Improvements relating to pumping systems and particularly to central lubrication systems for vehicles and machines
IPC: F16N13/02
Filed: 1944-05-11
Abstract: 586,756. Forced feed lubrication. TECALEMIT, Ltd., and LE CLAIR, C. C. S. May 11, 1944, No. 9040. [Class 12 (iii)] [Also in Group XXVIII] A pump (or pumps) having a rapid discharge stroke supplying lubricant to one or more points on a machine, engine, or vehicle, is operated by a piston or other fluid-actuated member in a cylinder supplied with pressure fluid under the control of a rotary valve element driven through reduction gearing from a rotary driving or driven part of the machine, engine, or vehicle. In Fig. 1, the shaft 6 of a vehicle engine rotates through a 700:1 reduction gearing enclosed in a box 5 a valve 1 connecting alternately a compressed air supply pipe 2 and an exhaust pipe 50 to a pipe 3 connected to a cylinder 4 containing a spring-returned piston 8 which operates through a linkage 10, 11, 12 multiple unit reciprocating pumps 13a, 13b delivering lubricant to the required points. The valve 1 comprises a rotating distributing member 29, Figs. 5 and 8, formed with a segmental transfer port 29a revolving over parts 34, 35, 36 connected to the pipes 2, 3, 50 respectively. The member 29 is connected by a pin 32 to its driving shaft 28 and is pressed by a spring 37 in the valve casing assisted by the pressure fluid against a plate 30 in which the ports 34, 35, 36 are formed. The size of the ports and passages renders the strokes of the piston rapid compared with the time for a complete cycle of operation. Fig. 9 shows another construction in which the pressure fluid is delivered and exhausted alternately to the opposite ends of a cylinder 42 containing spaced pistons 43, 44 rocking an oil-pump operating shaft 47. The oil-pump may consist of two parallel bands of identical pumping units 56, Figs. 10 and 11, constructed as described in Specification 567,644 and mounted on hollow containers 57, 57A, bolted to a base piece 58 formed at the top with a cylinder bore 59 containing the fluid operated pistons. The pistons rock a shaft 62 corresponding to the shaft 47 and carrying pump operating levers 72. Oil is supplied to the interior spaces of the containers 57, 57A and the base piece 58 through an inlet 78, these spaces forming a reservoir feeding the units 56. The reservoir is provided with an air vent connection 79. The pumping units may alternatively be constructed as described in Specifications 389,717, 432,235, 567,037 and 567,644, [all in Group XXVIII].
