Abstract

1358473 Hydraulic accumulators KLOCKNER - HUMBOLDT -DEUTZ AG 7 Feb 1972 [16 Feb 1971] 5554/72 Heading F1D An hydraulic accumulator comprises a variable volume liquid storage chamber 1 defined by an elastomeric bladder 2 having a peripheral head 3 held between the two parts of a housing 4. The two walls of the bladder 2 are acted upon by spring-loaded pistons 9, 10. The chamber 1 communicates with a fuel injection pump through a sleeve like extension 7 of the bladder 2.
