Abstract

1329395 Reciprocating pumps TOKYO KEIKI K K 3 Feb 1972 [27 Feb 1971] 5128/72 Heading F1A A pump assembly comprises a variable delivery pump submerged in the oil to be pumped in a tank 23 and driven by a motor 22, the assembly being mounted by vibration-proof members 38 in a lower compartment 28 of a housing 25 supported by vibration-proof members 40, the upper compartment of the housing having a cooling fan 30 which draws cooling air over the pump assembly via apertures 37b, 29 and 37a. Tank 23 has cooling fins 36. The pump has a swash-plate with pressureresponsive and manual control, Fig, 4 and 5 (not shown). The pump casing has air-release and drain holes.
