    摘要: An object of the present invention is to reduce the pressure loss in a relief valve employed for a high-pressure liquid supply pump. Disclosed is a high-pressure liquid supply pump for pressurizing a liquid and supplying the pressurized liquid from a low-pressure side to a high-pressure side. The pump includes a relief path which releases the pressurized liquid from the high-pressure side to the low-pressure side, and a relief valve which is positioned in the relief path and equipped with an intermediate chamber, a valve seat positioned toward the high-pressure side of the intermediate chamber, a ball valve that is attachable to and detachable from the valve seat, and a ball valve retainer for pressing the ball valve against the valve seat. The relief path is configured so that an inflow path to the intermediate chamber and an outflow path from the intermediate chamber both produce a restriction effect. The ball valve retainer has a pressure reception surface for receiving the pressure from the intermediate chamber. A first pressure reception area, which detaches the ball valve from the valve seat upon receipt of liquid pressure of the pressurized liquid from a high-pressure section when the relief valve closes, is smaller than a second pressure reception area, which lifts the ball valve and the ball valve retainer upon receipt of liquid pressure from the intermediate chamber.

    摘要: A high-pressure fuel supply pump which has no probability of discontinuity of a thin film of fuel at a sliding portion even when the fuel is not needed to be compressed to a high pressure is obtained. Two low-pressure fuel ports are provided on the high-pressure fuel supply pump in addition to a high-pressure discharge port to a high-pressure fuel capacity chamber. One of the two low-pressure fuel ports is connected to a low-pressure fuel capacity chamber and remaining one is connected to a low-pressure fuel supply pump. Accordingly, the interior of the high-pressure fuel supply pump is always filled with fresh fuel even in a mode in which a high-pressure fuel injecting valve does not inject fuel and only a low-pressure fuel injection valve injects fuel, so that a temperature rise of a plunger and a cylinder is prevented and locking of the plunger and the cylinder can be prevented.

    摘要: One of a plurality of data display formats with different units of correlation data that are prepared in advance is automatically selected depending on the variation of the amount of data in terms of the number of items thereof. One of a plurality of display methods with different summarization levels that are prepared in advance is also automatically selected for information (about correlation data or individual events) regarding individual cells. Information about the correlation data and individual cells is then displayed. The amount of work required to repeat the operation of observing the correlation data as a whole and the detailed observation of a small amount of data is reduced in a method for visualizing correlation data concerning two events in a matrix format.

    摘要: Provided is a small, simple-structured, homogeneous and mass-producible excessive pressure release valve which works even at a relatively low excessive pressure to surely and safely release the pressure to the external world. The excessive pressure release valve has an elastic rubber plate and a reversibly openable slit that passes through the upper and the lower surfaces and release the pressure to the external world when the internal excessive pressure stressing on the lower side surface, pushes and opens the slit toward upper surface side. The elastic rubber plate is made of silicone rubber containing 1-20% by mass of silicone oil.
