Abstract: A pneumatic spring for vehicles which spring includes two supports as well as at least one closed spring volume and two differently sized spring areas which are subjected to a pressure acting in opposite directions. The two spring surfaces are separated from one another and are variable in size as a function of the travel of the pneumatic spring, two roll bellows are arranged in a casing of the pneumatic spring with opposite spring surfaces of the bellows being supported upon connected spring pistons. The supports are formed, on the one hand, by the spring pistons and, on the other hand, by a casing associated with the walls of the roll bellows. Partial volumes are defined by the roll bellows with the partial volumes being separated from one another so as to maintain the respective volumes essentially independent of the travel of the pneumatic spring.

Abstract: An installation for the continuous measurement of the fuel consumption of internal combustion engines, in which a fuel-metering member predetermining with its position the through-put fuel quantity as a function of displacement. A preferably electrical displacement pick-up is coupled with the fuel-metering member which produces an analog signal corresponding to the deflection of the fuel-metering member from its normal position while an instrument for the indication of the signal is arranged within the field of vision of the operating person.
