摘要： A brake booster of positive pressure type includes a valve mechanism to which a positive pressure such as compressed air from a source located externally of a shell is fed for switching a flow path, through a conduit disposed within a constant pressure chamber disposed forwardly of a power piston and a supply passage which is formed in a valve body. The supply passage according to the invention comprised a radial passage which extends radially outward through the valve body from a shank portion thereof, and an axial passage which communicates with the radial passage, which an opening of the radial passage into the peripheral surface of the valve body being closed by a seal member which may be formed of an elastic material such as rubber. The seal member is covered by part of the power piston. This construction permits the supply passage to be formed in an inexpensive manner as compared with a formation of a supply passage which extends obliquely through the valve body. The power piston reliably prevents the withdrawal of the seal member from the radial passage.

摘要： A brake booster of tandem type includes a valve body, a rear power piston, a front power piston and a centerbody slidably extending through a centerplate which is centrally disposed within a shell, all of which are integrally connected together by utilizing a hub. An end of the hub located adjacent to the valve body is formed with an engaging portion which extends radially outward, while the shank portion of the valve body is formed with an axial groove which permits the engaging portion to pass there through and is also formed with an engaging recess circumferentially displaced from the axial groove and receiving the engaging portion. The engagement between the engaging portion and the engaging recess allows the hub to be assembled with the valve body while preventing the withdrawal of the hub forwardly from the valve body and also preventing the relative rotation therebetween, all with a greatly simplified construction.

摘要： A flow control valve in which the hydraulic pressure difference exerted on a spool valve is controlled by regulating the degree of throttling of a variable orifice and the oil which is discharged from an oil pump is partly returned to the suction side of the oil pump in response to the degree of actuation of the spool valve according to the above hydraulic pressure difference, thereby controlling the quantity of oil that is fed to hydraulic devices. The flow passage to communicate the oil pump with the hydraulic devices includes a flow passage which permits the hydraulic oil to pass through a hole in which the spool valve is fitted, and a variable orifice is composed of an opening of the flow passage into the hole and a small diameter portion formed on the spool valve. The throttling of the variable orifice is attained by covering the opening with a predetermined clearance by the above small diameter portion.

摘要： A drive circuit for a solenoid pump comprises a series combination of a pump solenoid and a capacitor connected through a rectifier circuit with an a.c. source. The solenoid is shunted by another rectifier poled to pass a charging current to the capacitor. A thyristor is connected across the series combination, and is triggered into conduction, whereupon it short-circuits the series combination to permit a discharge of the capacitor through the solenoid and to prevent a current flow from the source to the capacitor, thus allowing a uniform control of the energy discharged by the capacitor. A trigger circuit for the thyristor comprises a relaxation oscillator including a programmable unijunction transistor, the conduction of which is controlled inversely to fluctuations in the source voltage.

摘要： An electrical energy stored in a capacitor is discharged to the solenoid of a solenoid pump through a thyristor as the latter is controlled to conduct, thereby producing a reciprocating movement of the piston of the pump. The value of the drive current passing through the solenoid is detected by a detection circuit, and a signal which depends on the magnitude of the drive current is applied to the trigger circuit of the thyristor. The period of oscillation of the trigger circuit which controls the conduction of the thyristor is controlled by the signal, whereby a uniform drive energy per unit time to the solenoid pump is assured.

摘要： A power steering valve system includes an input shaft and an output shaft which are aligned on a common axis, and also includes a control valve mechanism which is located offset from the axis in order to reduce the overall length of the valve system. The control valve mechanism includes a spool valve, a displacement of which from its neutral position controls the flow of a hydraulic oil from an oil pump to or from a power cylinder to assist in directing the steerable road wheels in a given direction. The input and output shafts are operatively associated with a motion translating mechanism which translates the magnitude of a relative torsion between the two shafts into a linear displacement. The motion translating mechanism is operatively associated with the spool valve to displace it from the neutral position in accordance with the magnitude of relative torsion between the two shafts.
