Patent number: 8997795Abstract: A flexible hose (1) has at least two textile reinforcement inlays or inserts (5, 6, 7) and an inner layer (2) made of elastomeric material. The flexible hose can assume various curvature geometries and, on the other hand, is still pressure-resistant because a textile reinforcement inlay (5) made of a peripherally closed, tubular knitted or woven fabric is applied to the elastomeric inner layer (2). A textile layer (6), which is rubber-coated on both sides, is wound as a further textile reinforcement inlay onto the tubular knitted or woven fabric (5).Type: GrantFiled: August 12, 2010Date of Patent: April 7, 2015Assignee: ContiTech MGW GmbHInventors: Ligia Ludwig, Gerhard Will, Robert Dill

Patent number: 7896400Abstract: A system for pre-positioning a hose clamp (2) on a hose end (24) includes: a) a fixing part (1?) which is connected non-releasably to an annular segment of the hose clamp (2) and is fastened to the hose end (24), and b) one or more fixing parts (1, 1?) which each have a U-shaped element which, fastened to the hose end (24), is directed with its open side (3) to the hose surface. The web (6) connects the two U-legs (4, 5) and extends axially and parallel to the hose surface. The U-leg (4), which lies closest to the hose end (24), has a connecting element (7) for attaching the U-shaped element to the end face of the hose end (24). The U-shaped element is configured in such a way that the hose clamp (2), which is pulled on to the hose end (24), is fixed releasably in the intermediate space (8) of the U-shaped element by way of an annular segment of the hose clamp in such a way that the hose clamp (2) is released from the fixing when tightened.Type: GrantFiled: February 25, 2009Date of Patent: March 1, 2011Assignee: ContiTech MGW GmbHInventors: Hartmut Brill, Matthias Dönch, Günther Speelmann, Gerhard Will

Patent number: 4355550Abstract: In order to diminish the lurching which occurs when automatic transmissions of motor vehicles perform gear changes, the invention describes apparatus for gradual changes of the engine torque at or near the onset of the gear change as well as at or near the time of gear reengagement. The engine torque may be changed by altering the fuel metering characteristics and/or the ignition timing in a gradual and controlled manner.Type: GrantFiled: September 28, 1979Date of Patent: October 26, 1982Assignee: Robert Bosch GmbHInventors: Gerhard Will, Walter Stroh, Martin Zechnall

Patent number: 4254671Abstract: For automotive vehicles having an engine which has a speed governor which is activated when the engine reaches the maximum permissible engine speed, an AND-gate is supplied which furnishes an upshift signal when the engine speed has reached the maximum permissible speed and when, simultaneously, the pedal is at the full load position or the kickdown switch is activated. The upshift signal is applied to the control circuit for the automatic transmission. It may be combined with a signal signifying vehicle speed in a direction so as to increase the apparent vehicle speed or with a signal indicative of throttle position to indicate an actual lower engine load than present.Type: GrantFiled: February 28, 1978Date of Patent: March 10, 1981Assignee: Robert Bosch GmbHInventors: Joseph Sauer, Volker Kadelbach, Gerhard Will

Patent number: 4253348Abstract: A comparator circuit compares an engine speed signal with an engine load signal, the latter being furnished to the comparator through transistors controlled by switching signals representative of the condition of the gear range selection lever, the kickdown switch and the magnetic valve that operates, when actuated, to shift from high gear to a lower gear. The circuit is operative only when the kickdown switch is unoperated and the gear range selection lever is in the "drive" position that permits operation in high gear. The magnetic valve position indication is coupled to the circuit through a differentiating network, so that the circuit comes into play only for a short interval following the switching over of the magnetic valve from the high gear position.Type: GrantFiled: December 27, 1977Date of Patent: March 3, 1981Assignee: Robert Bosch GmbHInventors: Gerhard Will, Walter Stroh

Patent number: 4250922Abstract: The electromagnetically operated sliding spool control valve particularly for use in connection with an automatic transmission system of a motor vehicle, comprises an armature of the electromagnet which is supported at one end of a plunger the other end of which is formed into a sliding spool. The spool is guided in a valve sleeve integrally connected to a fixed core of the electromagnetic coil. A return spring is arranged around a plunger portion between the core and the armature. The valve sleeve is seated in a central boring of a valve channel plate provided with a plurality of annular grooves communicating via transverse borings with the central passage of the sleeve. The sleeve opens into a pressure space which communicates via a flow return channel with a port for the main pressure so that the main pressure acts against the free end of the spool.Type: GrantFiled: May 24, 1979Date of Patent: February 17, 1981Assignee: Robert Bosch GmbHInventors: Gerhard Will, Walter Stroh

Patent number: 4233860Abstract: To permit placing an electrical-hydraulical controlled automatic transmission, selectively, in reverse or neutral position upon failure of the control or command system, a spool valve is interposed between a fluid pressure pump and the control unit, the spool valve having three positions in which it can be placed manually; one of the positions is its normal operating position in which the valve provides a straight fluid path for pressurized fluid from the pump to the control unit; the other two positions are operable under emergency conditions, a second position providing a connection directly from the valve to the hydraulic servo units associated with control of the reverse gear, and the third interrupting suppply of hydraulic fluid from the pump to the control unit so that the control unit will, effectively, be placed in neutral position.Type: GrantFiled: March 6, 1978Date of Patent: November 18, 1980Assignee: Robert Bosch GmbHInventors: Volker Kadelbach, Gerhard Will, Joseph Sauer

Patent number: 4222292Abstract: In order to be able to reduce the jolt produced by the transmission going into gear when the vehicle is standing still or moving only slowly, the shifting of the gear range selector lever from neutral gear into any drive range gear is caused to operate magnetic valves controlling the automatic transmission to set the transmission in the highest gear for a very brief period, enough to reduce the jolt, but not enough to interfere with the normal progress of automatic gear shifting.Type: GrantFiled: January 16, 1978Date of Patent: September 16, 1980Assignee: Robert Bosch GmbHInventors: Gerhard Will, Walter Stroh

Patent number: 3941016Abstract: A pump, driven by the engine, supplies hydraulic pressure as a function of engine speed; the engine controller provides a displacement force, for example by a cam, acting on a main valve slider, or spool of the switching pressure controller. To additionally provide a speed signal to the main spool, the switching pressure line, connected to the pump, has a Venturi, diaphragm, bent tube, or other constriction therein from which a hydraulic signal representative of engine speed can be derived, which hydraulic signal is applied as a force additionally acting on the main valve slider or spool so that the spool position, and hence output switching pressure, will be representative both of engine controller position as well as of engine speed.Type: GrantFiled: April 29, 1974Date of Patent: March 2, 1976Assignee: Robert Bosch G.m.b.H.Inventor: Gerhard Will

Patent number: 3937108Abstract: To permit continued operation of an electronically controlled gear change transmission in case of failure of electronic control signals, at least one three-way check valve is included in the system to connect, in one mode of operation, the normal output control signals from a hydraulic control valve system to engage an operating element (such as a control clutch, control band, or the like in the automatic transmission) and, when in another position, connect hydraulic pressure to effect connection of drive power to the first gear, or reverse (as selected by a control selector) and in the absence of electrical command signals from the electronic control unit. By use of a second three-way check valve, simple interlocks to prevent shifting into reverse when the vehicle is moving forward in excess of a given speed, and to permit holding of an engaged gear in case of malfunction, can be provided.Type: GrantFiled: October 21, 1974Date of Patent: February 10, 1976Assignee: Robert Bosch G.m.b.H.Inventor: Gerhard Will
