Abstract:
A hydrostatic bladder-type storage means for storing mechanical energy by a compressible media in a pressure bottle. An interior of the pressure bottle contains an elastically resilient bladder accommodating the medium. The pressurized medium is introduced into the bladder from one side of the bottle, with the bladder being surrounded by hydraulic oil which is adapted to be forced into and removed from a cavity located between the bottle and the bladder. A porous elastic body of foamed synthetic resinous material is provided in the bladder with the medium filling pores of the foam body. The foam body is intimately joined to the wall of the bladder and has a specific thermal capacity which is greater than the thermal capacity of the medium.
Abstract:
A method for producing a foam body, in particular for a pressure accumulator, such as a hydraulic accumulator, the bubble- or diaphragm-shaped, elastically flexible separating layer (12) of which separates two media chambers from each other within the accumulator housing, in particular a gas working chamber from a liquid chamber (18), with at least the following production method steps: —introducing a flowable, preferably liquid, foam material into the pressure accumulator, said foam material being at least partially surrounded by the separating layer (12), —curing the foam material in the pressure accumulator, and in the process—building up a pressure gradient, in which the visibly curing foam material expands the separating layer (12) from an originally partially filled starting state in the direction of an end state, in which the accumulator is finally filled with the cured foam (38).
Abstract:
A hydraulic control unit for a hydraulic vehicle control system, such as anti-lock brakes, includes a hydraulic accumulator including a housing that defines a cavity and a passageway that extends from the cavity and that is adapted for inner-connection with a host hydraulic circuit, preferably adjacent the high pressure outlet of the host system hydraulic pump. A closure member cooperates with the housing to substantially seal the cavity. A pre-loaded elastomeric member is disposed within the cavity and is compressible with increasing hydraulic fluid pressure to attenuate short duration pressure pulses therein. The elastomeric member is preferably enclosed within a rigid relatively porous member that, in combination with the elastomeric member, substantially fills the entire volume of the cavity and permits pressurized fluid to act on substantially the entire outer surface of the elastomeric member to minimize internal friction and hysterisis losses and provides the structure, along with the closure member, to pre-load the elastomeric member.
