    Abstract: In all hydraulic systems, it is important to remove all entrained air, dirt and other impurities from the system prior to normal operation. In the subject invention, a method of purging and/or preconditioning a hydraulic system is provided and includes the steps of connecting a shunt line between opposite ends of respective fluid actuators and operating the respective valve mechanisms to force fluid from the source of pressurized fluid through the respective valve mechanisms across the respective shunt lines and back to the reservoir. Likewise, the subject invention provides a method to purge the signal control system of any entrained air, dirt and other impurities. The method also provides an easy process of "warming up" the system or totally replacing all of the fluid in the system with another type of fluid, such as fluid for arctic conditions. The method of purging the signal control system includes selectively connecting a bypass line between the reservoir and the signal control system. The above method provides an efficient and simple way to purge a hydraulic system of entrapped air, dirt and other impurities.

    Abstract: In a hydrodynamic torque converter, an axial abutment is arranged to support friction discs of a lock-up clutch and a clutch actuator working pressure chamber accommodating an axial piston so as to move with a friction disc carrier. Together with a second friction disc carrier, the friction disc carrier torsionally holds the friction discs in alternating sequence and is also located in a centripetal flow between a pump impeller outlet and a torque converter return conduit.

    Abstract: A hydraulic drive system for a construction machine comprising a plurality of distribution compensating valves (7a, 7b) for controlling the respective differential pressures across the plurality of flow control valves (6a, 6b), the distribution compensating valves respectively having first pressure bearing chambers (52a, 52b) acting in a valve-closing direction, second pressure bearing chambers (53a, 53b) acting in a valve-opening direction, and third pressure bearing chambers (54a, 54b) acting in the valve-closing direction to reduce target values of differential pressures across a plurality of associated flow control valves (6a, 6b). The system further comprises a fourth pressure bearing chamber (55a, 55b) provided in at least one of the plurality of distribution compensating valves (7a, 7b) and subjected to a second control pressure (P.sub.CT) for acting in the valve-opening direction to set a target value (.DELTA.P.sub.T) of the differential pressure across the associated flow control valve (6a, 6b). This enables the target value of the differential pressure across the flow control valve to be freely changed whereby an allowable maximum flow rate passing through the flow control valve can be freely changed so that a maximum driving speed may be freely set dependent upon the capacity of a hydraulic actuator used and/or the forms of work to be carried out.

    Abstract: A hydrodynamic retarder has a centrally disposed chamber which is filled with hydraulic fluid and subjected to centrifugal forces. A valve mechanism, responsive to the operator, is opened by a control valve system when vehicle retarding action is requested to permit rapid filling of the retarder vane space from the centrally disposed chamber. The valve mechanism is also closed by the control valve system after a predetermined time. This accommodates fast filling of the retarder but does not permit air ingestion by the retarder. A passage, in the stationary housing portion of the retarder, is opened to the transmission pump circuit during retarding action to maintain the retarder pressure and fluid circulation for cooling. The central chamber has an air control valve to admit air to the chamber as the chamber empties of hydraulic fluid and to permit air exhaust therefrom when the chamber is refilled.

    Abstract: A lock-up valve includes a spool movable between a clutch engagement position wherein the lock-up clutch is engaged and a clutch release position wherein the engagement of the lock-up clutch is released. A spring biases the spool toward the clutch release position. The spool has a first pressure acting area and a second pressure acting area. A fluid pressure is applied to the first pressure acting area during operation in the m+th speed ratio (where: m is an integer) and the m+1th speed ratio to urge the spool against the spring toward the clutch engagement position. A lock-up timing valve is provided which allows the application of another fluid pressure to the second pressure acting area during shifting between the m th speed ratio and the m+1th speed ratio to urge said spool toward the clutch release position.

    Abstract: A viscous coupling adapted to be positioned within the housing of a torque converter automatic transmission for use as a bypass of the torque converter and including an annular clutch lining secured to a side face of the outer peripheral portion of the coupling and a control valve assembly positioned in the outer peripheral portion to cushion the impact of engagement of the annular clutch lining with the confronting surface of the torque converter housing. The control valve assembly includes a rolling diaphragm which extends across the open end of an axially extending bore in the outer peripheral portion and is arranged to rollingly traverse the bore to successively cover or uncover a series of axially spaced leakage holes communicating with the main chamber of the torque converter and the bore. The end of the bore remote from the diaphragm communicates with the side of the coupling carrying the annular clutch lining at a location radially inwardly of the clutch lining so that, upon initial engagement of the coupling, leakage flow may occur through the leakage holes from the main chamber of the torque converter to the other side of the coupling to cushion the impact of the clutching engagement and the leakage flow is thereafter gradually cut off to apply the full clutch force as the rolling diaphragm traverses the bore to successively cover the leakage holes.
