Abstract: PURPOSE:To eliminate useless work of an oil pump, and prevent an increase in a mechanical loss by optimizing distribution of a cam shaft bearing part requiring lubricating oil quantity and a cam surface requiring lubricating oil quantity. CONSTITUTION:When an engine is operated at high speed, lubricating oil distributed to a cam bearing supply passage 7 from a lubricating oil main passage 2 according to a rotational increase in a cam shaft 5a, is supplied to a pump chamber 9 arranged in a cam shaft bearing part 5, and the lubricating oil whose pressure is increased by rotation of the cam shaft 5a, is flowed into an oil pressure chamber 8b through a communicating passage 10, and pressure in the oil pressure chamber 8b is increased. At this time, an elastic body 8a expands until reaction of the elastic body 8a of a throttle valve 8 and pressure in an orifice part 8c can balance with the pressure in the oil pressure chamber 8b, and since an opening area of the orifice part 8c is reduced, a lubricating oil supply quantity supplied to a cam surface through an oil distributing pipe 4 from a cam surface supply passage 6, is reduced according to the rotational increase in the engine.

IPC: B60G17/015
Filed: 1988-12-26
Abstract: PURPOSE:To increase comfortability during driving in low speed zone and increase steering stability in high speed zone by, when a relative amount of variation between a wheel and body exceeds a specified limit within a specified time of period in vehicle speed below a specified limit, measuring the specified time of period again from that time, in a titled device for vehicle.

Title: Reciprocating pump
Inventor: KUNIMOTO ETSUO
IPC: F04B43/08
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To enable low viscous fluid such as water and liquefied gas to be fed under pressure without deterioration of a pump action by providing a bellows for dividing the inside of a pressure chamber partitioned by a piston in the flowing body side and the piston side, and a pressure equalizer for leading the pressure upstream from a suction valve into a drain groove on a piston external periphery. SOLUTION: When a piston 2 is driven so as to increase the oil pressure inside of an oil side pressure chamber 31, the pressure inside of a liquid side pressure chamber 32 is also increased so that the fluid inside of the liquid side pressure chamber 32 may be emitted from a delivery valve 5. Then, when the pressure inside of the oil side pressure chamber 31 is decreased when piston 2 descends, a bellows 30 is elongated by means of a spring 33 so as to allow the fluid to be sucked in from a suction valve 4.  In this case, a pressure equalizer 14 whose inside is divided into an oil side uniform pressure chamber 41 and a liquid side uniform pressure chamber 42 by means of a bellows 40 is provided so that the oil side uniform pressure chamber 41 is communicated with the inside of a crank chamber 11 and the liquid side uniform pressure chamber 42 is communicated with the liquid side jointed to the suction valve 4 and the delivery valve 5. Thereby, a large differential pressure between the inside and outside of the bellows 30 is suppressed so as to prevent pump liquid from leaking outside.
