Patent DE-3841462-A1 (DE)
Inventor: RIZK REDA R
IPC: F02M59/48
Filed: 1988-12-09
Abstract: The invention has the object of improving a known fuel injection device, which comprises an injection pump element with an electromagnetically actuated control valve body, mounted in the latter, for controlling the beginning of delivery and the delivery quantity, in such a way that the injection pump element and the control valve are individually exchangeable and that the control valve body moves onto its seat without rebound. 
<??>The solution comprises a control valve (2) which is arranged with clearance in a stepped hole (19) of a plunger sleeve (5) and is mounted in sealing elements (20). The freedom from rebound is achieved by matching a minimum spacing (46) between an armature plate (30) and an electromagnetic regulating device (7), the armature plate (30) being situated in a fluid-filled damping space (33) and the minimum spacing (46) being optimised as a function of the mass of the moving parts of the control valve (2), the spring stiffness of a control valve seat (25), the geometry of an armature plate (30) and the viscosity of the fuel in the operating temperature range. 
<??>The invention is suitable for diesel engines.

The retaining means is composed of an upwardly open sleeve 4 which, in the lower region, exhibits a guide plate 6 having a continuous bore for the through-passage of a long anchorage rod 3. The anchorage rod is fastened, at its upper end, in a piston 2. The piston 2 is provided with an opening which is directed perpendicularly with respect to the anchorage rod 3 and is intended for receiving a pin 1, a locking device, e.g. a locking clamp with pin. The pin 1 partially projects, with its free end, in the uppermost position, into a nut 8 connected to the sleeve 4, with the result that the pin 1 cannot be erroneously displaced during transportation. The nut 8 serves, furthermore, for screwing in a fixing device 9 which serves, in the operating state, for arresting, for example, a sunshade. The sleeve 4 is ... with a plurality of bores 5, 7 which are provided at equal or non-uniform intervals and are intended for receiving the... Original abstract incomplete. <IMAGE>

Title: Compensator for pipe temperature and pressure fluctuations - uses compression diaphragms fitted inside pipes
Inventor: LEONHARD HANS
IPC: F16L57/00
Filed: 1990-01-02
Abstract: The compensator is for preventing the bursting, cracking or damaging of pipes or pipe and pressure vessel circuits by fluctuations in the temperature, volume or pressure of the medium flowing in the pipes. The method consists of inserting air or gas compression diaphragms into the pipes or pressure vessel so that the reduction in volume of the compression diaphragm is equal to the increase in volume of the medium flowing in the pipes.  These compression diaphragms are so designed that the surrounding medium does not penetrate into the diaphragms. The compression diaphragms are joined together to form one large functional unit which does not impede the flow of the medium through the pipes. USE - Prevention of damage to pipes.
