摘要： A control valve have a main channel, a channel cross section adjustment spool, a downstream side branching channel, a communication channel, a channel open and close spool, a channel open and close valve, and a upstream side branching channel. In a low rotation speed region of an engine, the channel open and close valve blocks the communication channel. In a medium rotation speed region, the channel open and close spool allows the communication between the downstream side branching channel and the communication channel, and the channel open and close valve allows the communication channel to communicate to slide and move the channel cross section adjustment spool in a direction. In a high rotation speed region, the channel open and close spool blocks the communication between the downstream side branching channel.

摘要： The present invention provides an engine lubrication control system including an engine, an oil pump which is driven by the engine, an oil circuit which extends downstream from the oil pump, and a plurality of oil branch supply paths which branch from the oil circuit and supply oil to each part of the engine. An electronically-controlled first hydraulic control valve which controls, in a stepwise manner, a discharge pressure of the oil pump relative to a speed of the engine is disposed on the oil circuit, a hydraulically-driven second hydraulic control valve is disposed on at least one of the plurality of oil branch supply paths, and a downstream hydraulic pressure of the second hydraulic control valve is controlled to be lower than a downstream hydraulic pressure of the first hydraulic control valve of the oil circuit at least across a predetermined engine speed range.

摘要： A control valve have a main flow passage; a flow passage sectional area adjustment spool; a downstream side branch flow passage; a communicating flow passage; a flow passage opening/closing valve; a flow passage opening/closing spool; and an upstream side branch flow passage. The flow passage opening/closing valve cuts off the downstream side branch flow passage from the communicating flow passage in a low rotation region of an engine. In a medium rotation region, the flow passage opening/closing valve connects the downstream side branch flow passage to the communicating flow passage and the flow passage opening/closing spool allows the communicating flow passage to communicate. In a high rotation region, the flow passage opening/closing spool blocks the communicating flow passage.

摘要： A relief device for an oil pump includes a relief valve including a small diameter valve chamber and a large diameter valve chamber and a valve housing that includes a relief discharge section, a temperature sensitive valve, an oil pump, a main channel, a relief channel, and an auxiliary channel. The relief channel causes one side of the small diameter valve chamber and the large diameter valve chamber and the oil pump to always communicate with each other and enables oil to be discharged from the relief discharge section. The auxiliary channel enables the other one side of the small diameter valve chamber and the large diameter valve chamber and the oil pump to communicate with each other. The temperature sensitive valve is included in the auxiliary channel.
