Title: Hydrodynamic coupling
Inventor: DUMINY JACQUES
IPC: F16D33/12
Filed: 1984-07-23
Abstract: The filling level in the working chamber (13) of a hydrodynamic coupling can be varied due to the fact that rotating with the primary vane wheel (10) there is a storage container (15) for working fluid which can be transferred between this storage container and the working chamber by controlling admission of a compressed gas into the storage chamber. The storage container surrounds the radially outer region of the working chamber, and, in one case, is connected to the working chamber via at least two different fluid lines (28, 38). One (drainage) line (28) is designed for a constant flow of fluid from the working Fig. 2 chamber to the container, whilst the other (filling) line (38) is designed for a constant flow of fluid from the storage container to the working chamber, brought about by the pressure of the compressed gas. In another case, a fluid line (18) extends in the radial direction from said radially outer region into a fluid ring (16) formed, in operation, in the storage container (15), and means are provided for superimposing a pulsating pressure onto the compressed gas set pressure. <IMAGE>

IPC: B63C11/22
Filed: 1985-10-07
Abstract: The present invention provides an inlet valve assembly for a demand regulator divers valve having a valve body 21 to 23, an inlet duct 24, an outlet duct 25 and a valve member 26 in the valve body moveable between a first position in which the inlet duct 24 and outlet duct 25 are in gas flow communication and a second position in which there is no communication between said ducts, the assembly being characterised in that forces exerted by 24 inlet gas supply pressure on the valve member are substantially balanced such that relatively small forces are required to move the member between the said two positions. For example the inlet valve may be held closed by a light spring load acting on the inlet valve member. A preferred inlet valve assembly has an essentially dumbell shaped inlet valve member, and inlet duct pressure acts in a cavity 36 defined between the dumbell end portions and a surrounding valve body portion, and outlet duct pressure (relatively low) acts at the outer end surface of each end portion. <IMAGE>

Title: Vehicle rear suspension
Inventor: TOMS GEOFFREY STEPHEN
IPC: B60G11/34
Filed: 1987-10-28
Abstract: A vehicle rear suspension comprises, at each side of the vehicle, a U-section housing member (32) carrying a first resilient annular bush (24) providing a pivotal mounting bracket (34) secured to a body member (35) of the vehicle, and also carrying a second resilient annular bush (26) having a connection to the mounting bracket to provide resilient control of pivotal movement of the housing member. A third bush (28) provides connection for the suspension. One of the bushes may be replaced by a spring means. Generally vertically upwardly acting reaction forces acting at each rear wheel will produce pivotal movement of the housing member providing movement of the housing member providing movement in an upward direction at the control bush, with the overall suspension arrangement providing rear wheel roll understeer during vehicle cornering, whereas impact forces acting on a rear wheel as the wheel hits a bump will produce pivotal movement of the housing member providing movement in a downward direction at the control bush, so providing a resiliently controlled rearward movement of the rear wheel for cushioning the impact force. The suspension is typically of the leaf spring type, but the device is applicable to independent types as well. <IMAGE>
Patent GB-2219052-A (GB)
Title: Torque distribution unit
Inventor: LUCKING JEFFREY ROBERT
IPC: F16D41/10
Filed: 1988-05-25
Abstract: A device operationally similar to a conventional differential gear, comprises a number of roller elements 2 and 3 which are positioned in scallop within an outer drum 1, by frictional forces, governed by the demand of output shafts 9 or 10. The elements 2 or 3 transmit the torque from the outer drum 1 to inner hubs 4 and 5 via the reduced space within the scallops and the outer surface of the inner hubs 4 and 5. If either output shaft 10 or 9 increases rotational speed, the elements 2 or 3 associated with that shaft will travel to the clearance of the scallop and torque between outer drum 1 and relevant hubs 4 or 5 will cease with the torque then distributed to the output shaft 10 or 8, whereby output torque is distributed as required. <IMAGE>

Title: Piston pump powered by I.C. engine combustion chamber pressure
Inventor: ALLEN JOHN
IPC: F02M57/02
Filed: 1989-07-31
Abstract: A piston pump (21) to supply fluid to an internal combustion engine has a stepped piston (4, 5) in a stepped bore (2, 3) with the opposite ends of the bore connected to a combustion chamber of the engine and a port (11) connected to a source of hydrocarbon fuel.
