Abstract: Bonnet apparatus to provide live-loading to a seal are described herein. An example bonnet assembly includes a housing having a recessed opening to define a shoulder and a sealing disc disposed within the recessed opening. A biasing element is disposed in the recessed opening between a flange of the sealing disc and the shoulder of the housing to provide a load to a seal to be disposed between the housing and the fluid device. The biasing element biases the sealing disc away from the housing and the biasing element enables the sealing disc to move within the recessed opening relative to the housing when the bonnet assembly is coupled to the fluid device.

Abstract: The present invention includes a device that comprises a suction jet pump, that is arranged in a reservoir pot and has a nozzle and a mixing duct provided downstream the nozzle and arranged perpendicular to a pot base of the reservoir pot. The outlet of the mixing duct has a deflection means, which the jet of the nozzle impinges when the mixing duct is unfilled and has an additional volume formed at the outlet of the mixer by an offset widening of the mixer duct. This additional volume prevents the column of liquid in the mixing duct from being forced out by the propulsion jet of the suction jet pump. Thus the lead time of the suction jet pump is approximately equal in all operating states.
