Brake equipment for a hydraulic vehicle brake system which has an actuating assembly and a feed pump secured elastically thereon. The two communicate with one another via at least one suction and pressure line each. To assure an inexpensive, dependable flexible line connection between component parts that move relative to one another, the suction and pressure lines are embodied as housing bores in the assembly and pump housings and for a liquid-tight connection of two successive housings bores at a time extending in the course of the lines in the assembly housing on the one hand and in the pump housing on the other, at least one connecting tube is disposed in two flush bearing bores in the assembly housing and in the pump housing. The connecting tube rests pivotably and longitudinally displaceably in the bearing bores sealing off the bearing bores.

An engine mounting has a first armature, a second armature, a bellows interposed between the first and second armatures, and an inertia mass. The inertia mass is mounted on the bellows and vibrates independently with the first and second armatures. A partition wall formed with a passageway is disposed within the interior of the bellows and divides same into two chambers. A valve is mounted on the partition wall to open or close the passageway. The valve is responsive to a difference in pressure between the two chambers and decreases the effective area of the passageway during vibrations of the bellows with large amplitudes.

The invention relates to a brake device for a hydraulic vehicle brake system. In this device, a return feed pump located in a feed pump housing is supported at several points between an assembly housing and a fastening plate and is movable relative to the other components. The mounting is done by screws resting in bearing tubes, the screws being surrounded by elastic damping sleeves in order to enable the elastic mobility of the feed pump housing. The line connections between the feed pump housing and the assembly housing are made by small connecting tubes resting in housing bores in the feed pump housing on one side and in the assembly housing on the other. The through bore extending through the feed pump housing in this region is sealed off on the side of the feed pump housing opposite the small connecting tubes by bolts, which with their part remote from the feed pump housing rest on the fastening plate.

The excitations from the engines of launch vehicles and the aerodynamics of flight produce large vibrations which are highly detrimental to spacecraft during launch. Significant dynamic loads often exist in all three translations and for rotations as well, therefore, complete six degree-of-freedom vibration load isolation is often desired. The disclosed device utilizes a previously disclosed passive axial vibration isolation device to simply and effectively create a passive three-axis vibration isolation device suitable for effecting a six degree-of-freedom whole-spacecraft passive vibration isolation system. The vibration isolation system design can be simply tuned to address various dynamic load frequency bands of concern, including isolation for pyrotechnic shock. The resulting system is compact and lightweight and can be easily utilized with existing launch vehicle-to-payload support structures.

Excitations from engines of the launch vehicles and the aerodynamics of flight produce large vibrations which are very detrimental to spacecraft during launch. Whole-spacecraft vibration isolation systems that greatly reduce the transmitted structure-borne vibrations to the spacecraft are disclosed. The disclosed devices, when combined together into an isolation system, provide vibration isolation for the complete spacecraft and are the only connection between the spacecraft and the launch vehicle. Devices that provide isolation in the axial (thrust) direction are disclosed. These devices consist of an arrangement of damped metallic flexures and machined springs, which provide relative flexibility in the desired direction. Passive damping is provided by compressing and shearing viscoelastic materials.
