Abstract: A damper for a weighing device including a cavity 4 in which a plate 12 can move, which plate is designed for being connected to a weight measuring device 2. The cavity 4 is closed tightly by a flexible membrane 14 and is partly filled with an oil, while leaving a volume of air or of a gas between the top 14a of the oil and the membrane 14, the plate 12 being totally immersed in the oil. The lower surface of the plate 12 and the bottom of the cavity 4 have shapes which are not planar and which are not parallel to each other, thus preventing the formation of a thin film of oil between them. The peripheral surface of the plate 12 and of the peripheral wall of the cavity 4 define therebetween a first constriction 15 of which the transverse section is constant whatever the position of the plate 12 in the cavity 4.

A preload is applied either to the housing or to the seal cover to thereby bias these elements to compensate for volumetric changes in the chamber.

Abstract: In a self-pumping type hydraulic shock absorber, an outer cylinder is provided to cover an outer circumferential surface of a cylinder. The outer cylinder is formed to have a small-diameter portion, a mid-diameter portion and a large-diameter portion. A reservoir is formed between the large-diameter portion and the cylinder to communicate with upper and lower cylinder chambers. A cylinder member is fitted onto the mid-diameter portion and the large-diameter portion of the outer cylinder to form an oil tank between the cylinder member and the outer cylinder. A suspension spring (a coil spring) is provided between a spring seat attached to the small-diameter portion of the outer cylinder and a spring seat connected to a piston rod. Thus, the reservoir and the oil tank are provided inside the coil spring, so that each of the reservoir and the oil tank can be made to have a sufficiently large volume and the hydraulic shock absorber requires less space for mounting.

Abstract: A vibration damping device for mounting between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with the outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to the other portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid transfer duct between fluid chambers formed on opposite sides of the piston within the piston chamber. A plurality of spaced metal electrode bands are mounted on an inner surface of the outer housing and are electrically isolated therefrom and communicate with the fluid transfer duct for applying voltages across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device.
