Patent DE-4106098-A1 (DE)
Inventor: LANG VOLKER PROF DR
IPC: A61M16/00
Filed: 1991-02-27
Abstract: A device for producing a continuous positive pressure in the respiratory passages during spontaneous breathing is described. Respiratory gas is introduced, under overpressure with modulated pressure oscillations, through nasopharyngeal tubes (9) into the nasopharyngeal-oral cavity (16) or through a special oropharyngeal tube with pressure-measurement channels (flexible tubes) (12, 13) and a wide-lumen gas supply channel (flexible tube) and a narrow-lumen venting channel. In this way, even large leaks in the mouth region can be compensated. To ensure the constancy of the desired therapeutic positive pressures in the nasopharyngeal-oral cavity (16) and the respiratory passages and lungs, which communicate with the nasopharyngeal-oral cavity (16), continuous electrical-electronic measurements are carried out on the pressurized gas by pressure probes (11) in the nasopharyngeal-oral cavity (16), and the supply of fresh respiratory gas is regulated in function of these measurements. Obstruction of the pressure probes (11), e.g., by nasal mucus, is detected immediately by the absence of oscillating pressure signals and any differences in pressure registered by the pressure probes (14, 15), and generally cleared due to the activation of an automatic blow-through device for the probes. Only in rare cases would an alarm be triggered.

IPC: F01L1/344
Filed: 1991-10-26
Abstract: The invention concerns a hydraulic control device for turning the camshaft (10) of an internal-combustion engine. A sprocket wheel (12) driven by the engine is linked, by means of a linkage element (19) and helical gearing (18) plus straight-tooth bevels (21), with the camshaft (10). Translational motion of the linkage element produces relative rotational motion between the drive sprocket (12) and the camshaft (10). The translation motion of the linkage element is produced by a hydraulic piston (25) acted on by a radial-piston pump (39, 40) which is located in the control device and which aspirates hydraulic fluid out of a reservoir located in the engine and feeds it through outlet valves (47) to the pressure spaces (29, 30) each side of the hydraulic piston (25). Connected to one of these pressure spaces (29) is an electromagnetically operated pressure-control valve (70) which is opened by appropriate actuation of the electromagnet (76), thus decreasing the pressure in the pressure space (29) in front of the hydraulic piston (25). The control device described, which is extremely compact in design, is illustrated in the figure 1.
