Abstract: A head unit device for controlling motion of an object includes a chamber filled with a shear thickening fluid (STF) and a piston. The piston is housed within the chamber and exerts pressure against the STF from a force applied to the piston from the object. The STF is configured to have a decreasing viscosity in response to a first range of shear rates and an increasing viscosity in response to a second range of shear rates. The piston includes at least one piston bypass between opposite sides of the piston that controls flow of the STF between the opposite sides of the piston to selectively react with a shear threshold effect of the first range of shear rates or the second range of shear rates.

Abstract: Known pressure regulator valves for motor vehicles are comprised of a relatively large number of individual parts that have to be assembled at a high cost. In the pressure regulator valve set forth, the stop piece and the housing part are injection molded. This reduces assembly costs in the manufacture of the pressure regulator valve. The pressure regulator valve is particularly suited for fuel delivery systems of motor vehicles with an internal combustion engine.

Abstract: The pressure-regulating valve is provided with a cap which is formed by a tubular lower part made of plastic and a cup-shaped upper part made of plastic. The lower part and the upper part partially overlap, as a result of which it is possible to modify the force of the compression spring, which acts on the upper part, by displacing the upper part Once the spring force has been set, the lower part and the upper part are fixed relative to one another. The pressure-regulating valve is particularly suitable for use in fuel supply systems.

Abstract: A pressure regulating device is proposed which regulates the fuel pressure in a fuel injection system for internal combustion engines. The pressure regulating device includes a pressure regulating valve which has a valve diaphragm fastened in a valve housing and arranged to define a fuel chamber which communicates via inlet pipes with a fuel distributor line. Protruding into the fuel chamber is a valve seat body joined to the valve housing, on one end of which body a valve seat is formed and the other end of which engages an outlet conduit which protrudes through the wall of the fuel distributor line remote from the pressure regulating valve and is tightly joined to this wall.

Abstract: In known pressure regulating apparatus, the pressure regulating valve placed in a holder is provided with a plunge-cut sealing groove for receiving a sealing ring. A filter is also disposed inside the pressure regulating valve. The novel embodiment of the pressure regulating apparatus is intended to make it easier to embody and install the seal between the holder and the pressure regulating valve. To avoid a plunge cut on the bottom part of the valve housing of the pressure regulating valve, the bottom part is provided with a step, defining one side of a sealing groove, while the sealing groove bottom is formed by a restriction extending as far as one end face of the bottom part. The sealing ring is defined on the other side by a ring, which is placed upon the restriction, and being connected with a filter disk extending radially inward and serves as a retaining means for the filter disk.

Abstract: A discharge system is proposed which serves to introduce volatilized fuel into an intake tube of an internal combustion engine. The discharge system includes a discharge regulation valve, which on one side is located at an outlet line of an absorber element that emits volatilized fuel and on the other side is located at an outflow line which leads to the intake tube downstream of a throttle device. The discharge regulation valve includes a bottom portion and a cover between which one end of a leaf spring is firmly fastened. The other end of the leaf spring is loosely guided in a gap between the bottom portion and the cover. An armature is joined to the leaf spring and a valve closing body is secured to the armature remote from the leaf spring. A core is secured on a magnet housing disposed in the bottom portion and has a through conduit, which at one end terminates at a valve seat.

Abstract: A pressure regulating apparatus which serves to regulate fuel pressure in a fuel injection system for internal combustion engines. The pressure regulating apparatus includes a pressure regulating valve, which has a valve diaphragm fastened in a valve housing and defining a fuel chamber, which communicates via an inlet conduit with a fuel distributor line. Protruding into the fuel chamber is a valve seat carrier body having a valve seat body, on which a valve seat is embodied, from which an outlet conduit leads to an outlet fitting. The pressure regulating valve is inserted into a holder bushing communicating with the fuel distributor line and is sealed off therefrom by a sealing ring disposed on the regulating valve. The axial fixation of the pressure regulating valve in the holder bushing is effected via a screw connection with a retaining body.

Abstract: A damper element is proposed which serves to damp a pulsating fluid flow, in particular to smooth out and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damper element includes a base and a cap, which are welded to one another and a damper diaphragm is clamped between these elements. The damper diaphragm, in order to prevent diffusion of the fluid into a damper chamber of the cap, is embodied either as a polyimide diaphragm or as a combination of a fabric diaphragm and a polyimide diaphragm. The clamping area of the cap is embodied as inclined slightly toward the damper diaphragm by an angle .alpha., so that a long-term fastening and sealing of the damper diaphragm is assured.

Abstract: A damping device is proposed, which serves to equalize and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damping device includes a damper element which has at least one damper diaphragm fastened in a damper housing and is arranged to define a fuel chamber which communicates via a feed pipe with a fuel distributor line. The feed pipe is oriented toward a flow tube which communicates with a fuel supply line and protrudes into the fuel distributor line. The fuel chamber of the damper element communicates via a further feed pipe with the fuel distributor line. The feed pipe and the flow tube are axially spaced apart from one another by a distance (A).

Abstract: A damper element is proposed which serves to damp a pulsating fluid flow, and in particular to smooth out and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damper element includes at least one damper diaphragm which is fastened in a damper housing and defines a fluid chamber on one side. A connection fitting is disposed on the damper housing and is inserted into a plug connection of a fluid flow cross section. A flow opening is embodied in the fluid flow cross section, being open toward the fluid chamber and toward the fluid flow cross section. The flow opening and the fluid flow cross section are penetrated by a flow tube arranged to protrude therethrough, and into which a first fluid line, which discharges into the fluid chamber, is embodied. Between the flow tube and the wall of the flow opening, an annular, second fluid line is embodied.

Abstract: A control device is proposed having a bimetallic element, one end of which is pressed into a holding groove provided on a metallic holder disposed in a housing. Fixed placement of bimetallic element over the lifetime of the control device is thus ensured. A method of making such a device is also proposed.

Abstract: A pressure control valve to control the pressure of a fluid in a fluid system so that it remains constant. This type of valve can be utilized as element of a fuel injection system for internal combustion engines, and has storage means which are independent of the valve member, and actuatable by the pressure of the fluid. The pressure control valve comprises a housing and a support assembly urged toward a valve seat by a control spring. Additionally, a storage spring in the support assembly urges a closing member toward the valve seat. The closing member is slidably received in a bore in the support assembly. The support assembly is connected to a membrane which is tensioned between the housing members. Other variations of this device are also revealed herein.
