060347000 | Having condition responsive or manually settable control means to regulate unit output | 9 |
20100236229 | FLUID TYPE POWER TRANSMISSION SYSTEM - A fluid type power transmission system includes a fluid type power transmission device and a control part. The fluid type power transmission device includes an inlet part and an outlet part for a working fluid. The fluid type power transmission device is configured to transmit power in response to circulation of the working fluid in the interior thereof. The control part is configured to control a pressure of the working fluid in the inlet part by regulating a pressure of the working fluid in the outlet part of the fluid type power transmission device. | 09-23-2010 |
20110005216 | VARIABLE DISPLACEMENT TORQUE CONVERTER - A variable displacement torque converter having a pump wheel rotatably driven to generate a flow of fluid, a turbine wheel rotated in response to the flow of fluid delivered from the pump wheel, and a stator wheel rotatably disposed in the flow of fluid from the turbine wheel to the pump wheel, the variable displacement torque converter includes an electric motor rotatably driving the stator wheel for adjusting an output torque to be output from the turbine wheel. | 01-13-2011 |
20110185718 | CLOSURE WITH THERMAL SAFETY FUNCTION FOR A HYDRODYNAMIC MACHINE - The invention relates to a closure with a thermal safety function for a hydrodynamic or hydraulic machine, in particular a hydrodynamic clutch, designed for use in a housing of the hydrodynamic or hydraulic machine which holds a working medium, wherein the closure has a closure body for screwing or inserting into the housing or mounting on the housing in some other way; the closure body has a passage into which a closure core is introduced, which closure core is connected, by means of a melting element which can be melted on at a predefined temperature, directly to the closure body or to an intermediate element introduced in a seal-forming fashion in the closure body, in such a way that the passage is sealed off so as to prevent the working medium from passing through. The invention is characterized in such a way that the closure core has a blind bore or a blind hole which is open with respect to the working space, with the result that working medium can flow into the closure core. | 08-04-2011 |
20120180466 | Switch and Control Device and Drive Train for a Hydrodynamic Machine - The invention relates to a switch and control device for setting the power or torque transmission in a hydrodynamic machine, comprising at least one primary wheel and a secondary wheel, which together form a working space that can be filled with a working medium—comprising a housing that is composed of a main body and two shells; at least one electronic component that is at least indirectly used for controlling and/or monitoring the hydrodynamic machine or a predetermined state of said machine; at least one control valve that can be actuated by means of the electronic component in order to control a working medium flow in the hydrodynamic machine or into or out of the hydrodynamic machine. | 07-19-2012 |
20130111891 | VEHICLE DRIVE DEVICE - A vehicle drive includes a speed change mechanism connected to a rotary electric machine; an output member connected to the speed change mechanism and wheels; an engagement device changes a state of engagement between an input member connected to an engine and the speed change mechanism; a hydraulic pump driven by the engine or the rotary electric machine; a first pressure control device that controls pressure supplied from the pump and supplies the pressure to the speed change mechanism; a second, separate hydraulic pressure control device that controls the pressure supplied from the pump and supplies the pressure to the engagement device; and a case that houses the rotary electric machine, speed change mechanism, engagement device, and pump. At least the engagement device is housed in a space formed by the case, and the second hydraulic pressure control device is provided at a part of the case forming the space. | 05-09-2013 |
060348000 | Distributes motive fluid between plural units, stages or guides | 1 |
20090301074 | HYDRODYNAMIC ASSEMBLY WITH A RETARDER AND A HYDRODYNAMIC CLUTCH - The invention relates to a hydrodynamic assembly
| 12-10-2009 |
060352000 | Of means within an impulse, reaction or energy transfer flow path being adjustable to modify flow of motive fluid | 1 |
060354000 | Pitch or orientation of flow directing guide or blade controlled | 1 |
20160047469 | TORQUE CONVERTER HAVING VARIABLE PITCH STATOR - A transmission includes a torque converter stator with controllable blade angle. The blade angle is adjusted by adjusting the rotational position of a control ring with respect to a stator hub. The stator blades are supported by the stator hob, a locking ring, and an outer ring. The stator blades have teeth that mesh with teeth on the control ring to determine blade angle. A controller adjust the blades by commanding fluid pressures in hydraulic circuits routed to the stator hub. Various circumstances in which the controller would adjust the blade angle are discussed. | 02-18-2016 |
