Patent DE-3821813-C1 (DE)
Title: Thermostatic valve, especially for heating systems
IPC: G05D23/12
Filed: 1988-06-29
Granted: 1989-11-30
Abstract: In the case of known thermostatic valves, a volume change in the hydraulic system by the supply of additional heating energy is carried out in order to reduce the room temperature, e.g. to lower it at night. This additional energy must be expended during the entire lowering phase. It is the object of the invention to ensure that the expenditure of energy for a volume change in the hydraulic system is required only for the adjustment itself and not for the maintenance of this position. According to the invention, this is achieved by virtue of the fact that the volume of the thermostat container is varied mechanically and that the adjusting element which performs the change in the volume is fixed mechanically in the new position.
Patent DE-3923488-C1 (DE)
Title: Integrated opto-electronic displacement sensor - has detector having pin-structure and V-grooves in which bent ends of fibre are positioned
IPC: G01D5/26
Filed: 1989-07-15
