Filed: 1986-11-07
Abstract: PURPOSE:To improve the quality of a product by providing the upper and lower dies having plural radiation grooves on the die face and rapidly cooling a heated circular plate spring material by subjecting it press-forming between the both dies. CONSTITUTION:The circular plate like spring material A on which plural radiation slits A2 are formed from a center hole A1 is prepd. A bowl like tapered face is formed respectively on the opposing faces of a lower die 10 and upper die 20 and plural lines of radiation oil grooves and circumferential oil grooves are formed by crossing as well. After heating a spring material A at the hardening temp. in a furnace in advance, it is set via a center jig 30 on the lower die 10 and subjected to hot press forming in the space with the upper die 20. The material A is rapidly cooled by circulating a cooling oil inside the oil grooves of both dies. The spring material A is subjected to hot pressure forming by positioning it accurately and uniform rapid cooling is executed, hence the quantity of a product diaphragm spring is improved.

Title: Displacement control device of variable displacement pump
Inventor: ABE TAIZO
IPC: F04B49/00
Filed: 1984-12-17
Abstract: PURPOSE:To enable a device to hold the pressure in a pressure line to a predetermined value, by actuating a quantity decreasing piston to control the displacement control device, when a delivery quantity exceeds a consumption value, and reversely actuating a quantity increasing piston to control said device when the delivery quantity is less than the consumption value. CONSTITUTION:The delivery pressure in a pressure line 110, reaching a load device not shown in the drawing from a delivery port 25 of a pump, acts on the right end surface of a quantity decreasing piston 18 via a branch pipe 26. Further if the delivery pressure increases, a slider 16 is moved leftward, causing a plate 15 to be moved in a right direction. As a result, an eccentric ring 13, integrally formed with the plate 15, swivels counterclockwise decreasing the eccentricity and a delivery quantity of the pump. In short, the delivery pressure increases when the delivery quantity exceeds a consumption value of the load device, and the delivery quantity is automatically decreased till it agrees with the consumption value. Reversely the delivery pressure in the pressure line 110 decreases when the delivery quantity is less than the consumption value, and a control device, actuating a quantity increasing piston 28 and controlling the delivery quantity of the pump, enables the delivery pressure to be held to a fixed value.
