摘要： PURPOSE:To considerably decrease working time and to lower manufacturing costs by forming a cylinder block and a port plate into separate bodies and coupling both into one body by a frictional press-contact means. CONSTITUTION:A port plate 2 is formed into a ring shape having an outside circumferential wall 22 and an inside circumferential wall 23 having diameters equal to the diameters of the outside circumferential wall 12 and inside circumferential wall 13 of a cylinder block 1 by using a platelike material. This port plate 2 is formed by being blanked from a rolled steel plate or brass plate including a cylinder port 24 by a precision press. When the cylinder port 1 and the port plate 2 are frictionally press-welded, burrs 3, 4, 5 produced by upsetting are produced on the outer side of the walls 12, 22 of both, the inner side of the walls 12, 23 and the inside of the port 24. These burrs 3, 4, 5 are removed, and if necessary, a groove 7 for snap ring is engraved in the wall 13 of the body part 14, whereby the intended cylinder body is obtained.

摘要： PURPOSE:To elestically engage a retainer in the circumferential groove of a housing, by effecting press work to form the retainer, dispensing with a snap ring and providing a projection on the retainer. CONSTITUTION:A sheet is pressed to form an annular retainer 6 which is to support an oil seal 5. A flange 11 for manufacturing the outermost circumferential edge of the retainer 6 is made cylindrical. The retainer 6 is fitted on a cylindrical support wall 7 which is provided on the housing 1 concentrically with a rotary shaft 3. A liquid seal 20 is provided between the support wall 8 of the housing 1 and an annular main part 13 which is made continuous to the flange 11 and extends almost perpendicularly to the cylindrical surface of the flange 11. An engaing projection 17 is provided on the edge of the free end of the flange 11 so that the projection 17 extends outward in the radial direction. The projection 17 is elastically engaged on the edge of a circumferential groove 18 provided on the support wall 7. This results in dispensing with a snap ring and simplifying work.

CONSTITUTION:When an input shaft 11 is rotated by a engine, a counter gear 13 rotates through teeth 11, and an oil pump 21 provided in a front bearing retainer 15 at the left end of a mission case 12 through a drive shaft 20 is driven. Then, lubricating oil at the lower part of the mission case 12 flows through a filter 24, a through hole 23a and a pump 23, and is sucked up into the pump 21 from a suction port 21a, and exhausted to a space R through an exhaust pressure control valve 22 from the exhaust port 21. After lubricating bearing B3 and B1, the lubricating oil flows down towards the lower part of the mission case 12, on one hand, and flows through oil holes 11d and 11e and a pipe 26. After lubricating the bearing B2, the lubricating oil flows down towards the lower part of the case 12.

摘要： PURPOSE:To make an oil pressure regulating mechanism compact, by integrating a high pressure relief valve with a bypass valve. CONSTITUTION:When a vehicle is running, an upward force is applied to a pilot valve 94 by a piston 98 and a spring 95. When the pressure of a line P1 applied to a port 97 rises, the pilot valve 94 is pushed downward and a port 93 is opened and pressure oil is conducted from a chamber 91b to a line P0. A piston 91 is moved down by the difference between the pressure P1 and that in the chamber 91b to reduce the pressure P1. Then, the port 93 of the pilot valve 94 is closed to equilize the pressure P1 to that in the chamber 91b. The pressure of a line P13 is low and a piston 96 is at bottom dead center except when the vehicle is running. When the pressure of the line P1 rises to a relatively low set level, oil inside the piston 91 flows out to the line P0 through the port P93 and the pressure in the chamber 91b decreases. At that time, the piston 91 falls, a port 97 communicates with a port 98 and the function of the bypass valve is fulfilled.

摘要： PURPOSE: To provide a combined valve device which has a relief function, a function of short circuit escape in neutral position and a fluid replenishing valve function, by providing a plurality of springs to energize and hold valves in a balancing elastic manner.
CONSTITUTION: When the discharge quantity and discharge pressure of a pump PE increase, a pressure difference Pa-Pc also increase. When the pressure Pb of a right chamber 11b has become almost equal to pressure Pa, a valve 20 is moved leftward in accordance with the difference of the right and lift pushing forces to the valve 20 and a central valve 30 to close a port 12a. The closure of the port 12a by the valve 20 functions as a check valve for a short circuit. When the negative pressure on a suction side increases, the pressure Pb' of the right chamber 11b falls and the leftward pushing force to the valve 20 and the central valve 30 decreases. consequently, pressure Pc' of replenished liquid from a replenishing pump PA is received by a left chamber 11a' to move the valve 20 rightward to open a port 12a'. A relief function is fulfilled by the rightward movement of a valve 43 as an ordinary short circuit is formed.

摘要： PURPOSE:To enable connection to low pressure and high pressure passages with a balance piston valve housed in a valve body. CONSTITUTION:When a pilot valve 14 opens with an increase in a pressure of a chamber 17, the flow of a fluid produces a differential pressure before and after an orifice 16. The chamber 17 is communicated to a charging port 11 and the pressure of chamber 17 drops to produce a differential pressure before and after the orifice 16. When the differential pressure exceeds a specified level, a spool 23 is displaced to have a main port 10 communicating to the charging port 11 through a relief hole 24 thereby preventing a rise in the pressure in a high pressure passage 4. When the main port 10 is in a low pressure passage, the spool 22 is displaced to the left to have the charging port 11 communicating to the main port 10. A balance piston valve 13 comprises the spools 22 and 23.

CONSTITUTION: A block element 10 is equipped with a forced side through hole 11 and a main circuit side through hole 12. In a bottom part 15 of a cylinder hole 14 bored toward the forced side through hole 11 from an end face 13, a through hole 16 is bored to communicate with the forced side through hole 11, and its angular part 17 becomes a valve seat. Also the cylinder hole 14 communicates with the through hole 12 via a chamber 18, and at the same time a sleeve element 20, wherein a valve hole 22 is formed, is inserted into the cylinder hole 14. A valve body 26 equipped with a valve head 25, which can abut on and engage with a valve seat 17, is slidably inserted. And the valve body 26 has a valve head 25 separated from a valve seat 17 by a set distance by means of a balanced power of a first spring 28 pressing toward the valve seat and a second spring 29 pressing the valve body 26 against the first spring 28.
