Patent DE-4129970-C1 (DE)
IPC: A61M60/443
Filed: 1991-09-10
Granted: 1993-03-04
Abstract: In a blood pump casing (43) at least one piston (21a,21b) is disposed which is driven from a coupling point (19a,19b) on a triangular closed hypocycloidal track (Za,Zb), and which periodically compresses and releases a blood chamber (37a,37b). The one corner of the closed triangular hypocycloidal track points towards the piston, so that piston movements are produced which essentially comprise the three phases forward-stroke phase, return-stroke phase and stationary stroke phase.

Patent DE-4200918-C1 (DE)
IPC: F01P7/14
Filed: 1992-01-16
Granted: 1993-03-11
Abstract: The invention concerns a differential gear (3) driven by the crankshaft (1) of an internal-combustion engine and which distributes the drive torque as a function of the number of teeth on the differential gear (3) to engine auxiliaries (7, 11) driven by this differential gear (3). An exciter current (IE) fed to an auxiliary (three-phase alternator 7) is regulated as a function of load and/or cooling-water signals (SL, ST), and the drive torque (ML) to the alternator (7) varied accordingly. In order to maintain a constant alternator voltage (UB) the rotational speed (NL) of the alternator (7) is varied as is, by means of the differential gear (3), the rotational speed of another auxiliary (water pump 11). The cooling capacity of the engine can thus be controlled as a function of the cooling or load requirements.

Title: Sucking jet pump
Inventor: TREML CHRISTIAN
IPC: B60K15/077
Filed: 1994-01-14
Granted: 1995-04-06
Abstract: German Offenlegungsschrift 3941892 has already disclosed a sucking jet pump for use in a fuel tank. In this sucking jet pump, a propulsion jet discharging from a propulsion nozzle flows into a mixing chamber. This has the disadvantage that considerable pressure reduction takes place, which leads to an undesirable gas emission of the fuel. In the novel sucking jet pump, this disadvantage is to be avoided. This is achieved in that a number of spaced-apart auxiliary nozzles (10), but at least one auxiliary nozzle (10), are arranged at a distance from a discharge opening (6) of the propulsion nozzle (4), and in that the cross-sections "A2" of the inlet openings (9) of the auxiliary nozzles (10) in each case increase in accordance with the intended pressure reduction, the cross-section "A2" of the inlet opening (9) of the first auxiliary nozzle (10) being greater than the cross-section "A1" of the discharge opening (6) of the propulsion nozzle (4), and the cross-section "A2" of the last auxiliary nozzle being smaller than the cross-section "A3" of the housing section (22, 42) of the mixing tube (17, 40). <IMAGE>
