A hydraulic anti-skid apparatus for installation in a vehicle braking system includes a cut-off valve disposed within a braking circuit connecting a master cylinder to a wheel brake cylinder, a piston arranged to be applied at opposite ends thereof with a braking pressure from the master cylinder and a hydraulic power pressure from a power pressure source and being associated with the cut-off valve to open the cut-off valve while the power pressure is applied thereto and to be displaced by the braking pressure when released from the power pressure to close the cut-off valve and subsequently to increase a capacity downstream of the cut-off valve, a first changeover valve arranged to normally apply the power pressure to the piston and to exhaust the power pressure when a road wheel tends to be locked, and a second changeover valve arranged to permit the power pressure applied to the piston through the first changeover valve when the master cylinder is operated and to exhaust the power pressure therethrough when the master cylinder is released from its operation. The second changeover valve is loaded to maintain the pressure acting on the piston at a low level while the master cylinder is inoperative.

A hydraulic anti-skid apparatus for use in a vehicle braking system comprises a cut-off valve disposed within a braking circuit connecting a master cylinder to a wheel brake cylinder, a bypass valve disposed within a bypass passage of the braking circuit, and first and second pistons respectively arranged to control opening and closing operations of the cut-off valve and the bypass valve. A main body for the anti-skid apparatus is formed with a single cylinder the one end of which is closed by a closure member fixed thereto. To simplify the anti-skid apparatus in construction, the cut-off valve and the bypass valve are coaxially arranged within the single cylinder to be controlled by the first and second pistons respectively.

An actuator adapted to be used with the antiskid device of a vehicle and which includes cutoff valves which are capable of dividing each of the brake lines connecting the brake master cylinder of the vehicle to each brake cylinder at the wheels into two. The actuator further includes an electric motor and a high-pressure pump driven by the motor for forcing brake fluid into an accumulator. The brake fluid is also used as a mechanism for reducing braking effort when such are almost locked, i.e., for unlocking the wheels. The accumulator stores this unlocking fluid which is sufficiently pressurized to be greater than the maximum pressure that the brake fluid is under for braking action. Each piston taking the form of a right circular cylinder is advanced by the brake fluid and is withdrawn by the unlocking fluid supplied from the accumulator, so that the piston closes and opens the corresponding cutoff valve.

It is an object of the present invention to provide a magnetic recording/reproducing apparatus and its tape-pulling-out element capable of reliably holding a coupling element and stably carrying out tape threading. In a magnetic recording/reproducing apparatus, an end of a tape accommodated in a tape cassette 2 has a coupling element 8, the coupling element 8 is pulled out and the tape is taken up around a drive reel. The magnetic recording/reproducing apparatus comprises a leader tape 41 having one end connected to the drive reel, a tape-pulling-out element 40 connected to the other end of the leader tape 41, and a pulling-out element moving motor 51 for moving the tape-pulling-out element 40 into the tape cassette 2. The tape-pulling-out element 40 includes a first member 42 formed with a recess 42A, and a second member 43 connected to the first member 42 such that the second member 43 can be displaced, and the coupling element 8 is mounted on the tape-pulling-out element 40 by the recess and the second member 43.

An anti-skid device for motor vehicles provided with a hydraulic circuit for connecting the brake master cylinder with the wheelbrake cylinder has a first valve for dividing the hydraulic circuit into two sections, a second valve for supplying the hydraulic pressure to the pressure reducing piston and a third valve having two valve sections for controlling the hydraulic pressure supplied to a working fluid chamber so as to prevent it from exceeding a predetermined degree. The third valve is constructed so that a fluid chamber defined by both the slidable valve members and fixed valve members of the two valve sections is formed therein so as to be communicated with the working fluid chamber side circuit through an orifice, in order to prevent the generation of strange sounds from the third valve during its operation by damper action of the fluid chamber.
