| A traveling control method for performing a smoothing work or the like through an operation of a working device during traveling is provided. The traveling control method includes a first step of inputting a set value of a delay time of a traveling switching function of a traveling switching valve; a second step of inputting in real time an operation signal value according to a user's operation of a joystick and a traveling pedal; a third step of determining whether to operate the traveling and working devices according to the operation of the traveling pedal and the joystick; a fourth step of switching the traveling switching valve to a traveling switching mode through control of the electronic valve and returning to the second step when the traveling pedal and the joystick are simultaneously operated; a fifth step of determining whether the traveling pedal is operated and the operation of the joystick is temporarily stopped for a predetermined time; a sixth step of determining whether the set value of the delay time of the traveling switching function is larger than an initially set time required and switching the traveling switching valve to the traveling switching mode if the set value is relatively larger than the initially set time; and a seventh step of releasing the traveling switching mode of the traveling switching valve through control of the electronic valve and returning to the second step in the case where the traveling pedal is not initially operated, in the case where the traveling pedal is operated and the joystick operation has been stopped over the predetermined time, or in the case where the initially set time required is larger than the set value of the delay time. | ||||||
| 71 | HYDRAULIC SOFT START SYSTEM | US14601940 | 2015-01-21 | US20150128584A1 | 2015-05-14 | Edmund Joseph Zaleski; Paul D. Ellsworth |
| A hydraulic soft-start system includes a flow control valve which is in fluid communication with a pressure source and an inlet of a motor. The system includes a first flow restricting orifice and a second flow restricting orifice disposed between a pilot for actuating the flow control valve and the inlet of the motor. A first flow is passed from the pressure source via the first orifice to an inlet of the motor, placing the motor in a partially-actuated state. The flow control valve is actuated after a threshold pressure of the pilot is reached allowing a second flow to pass from the pressure source to the motor inlet. The second flow is higher than the first flow, thereby placing the motor in a fully-actuated state. | ||||||
| 72 | TIME DELAY VALVE | US13704399 | 2011-06-07 | US20130081725A1 | 2013-04-04 | Akira Arisato |
| An on-off valve (7) opens/closes flow between a port (P) where compressed air is supplied and a port (A) connected to the outside; and a delay mechanism (8) which opens the on-off valve (7) after a predetermined period of time. The delay mechanism (8) includes: a throttle valve (22); a piston (36); a pressurizing chamber (40); and a communicating passage (42). When a pressure of the compressed air supplied from the first port (P) to the pressurizing chamber (40) reaches a set pressure, a valve opening force exerted on the piston (36) exceeds a valve closing force exerted on the on-off valve (7), and the on-off valve (7) is opened, so that compressed air from the first port (P) is supplied to the outside through the second port (A). | ||||||

The device also comprises means (20) for modification of the output delivered by the means of power supply to the actuator, to allow the door to be opened more slowly in an initial phase of opening and more rapidly in at least one subsequent opening phase. | ||||||
| 74 | Traversing circular saw | US09873104 | 2001-06-01 | US20020092393A1 | 2002-07-18 | Doug Mains |
| A traversing circular saw device having a saw blade assembly mounted onto a cradle which can receive a number of logs to be cut into sections. The saw blade assembly includes a circular saw blade mounted onto an extension arm which is contained within an arm sleeve. The width of the cradle is greater than the diameter of the saw blade. The saw blade is extended across the cradle by a piston. One embodiment of the invention includes a charge accumulator for the hydraulic system which can time-delay engagement of the extension means. The system can also include a flow control valve for varying the time delay of the charge accumulator. | ||||||
| 75 | Device for time-dependent control of the duration of regeneration of an air dryer | US116894 | 1998-07-17 | US5953915A | 1999-09-21 | Rolf Weller |
| An improved adjustability and functional reliability of a device for time-dependent control of a duration of regeneration of an air dryer including a piston, which is longitudinally guided, displaceably counter to a resistance, in a cylinder by the force of a spring. The cylinder is closed by a cap, on which means for adjusting the prestressing force of the spring, supported at least indirectly on the cap, are provided. These means comprise a screw-wedge connection, which joins the cylinder and the cap to one another in such a way that by twisting the cap, an axial displacement of the cap relative to the cylinder is brought about. The device can be used for instance in air dryers for compressed air systems of motor vehicles. | ||||||

| A delaying device for a fluid system for operating a hydraulic motor (10) wherein electrically operated pilot valves (39,40) are actuated by limit switches (13,13') in the motor to control flow through pilot lines (37,38) into a control block (20) and then to and from the motor, said delaying device comprising a dashpot cylinder (46) connected to said pilot lines for momentarily continuing to supply fluid to said control block (20) after pilot valve (39 or 40) is shut off. | ||||||
| 77 | Timed input-output motion transmitting device | US3727480D | 1971-12-08 | US3727480A | 1973-04-17 | NEED L |
| A motion transmitting mechanism having a predetermined delay between input and output motion. Movement of the input is transmitted through a lost motion device, such as a spring, to an input piston. Movement of the input piston causes the displacement of a fluid medium which flows at a controlled rate through a restriction. Movement of the input piston is transmitted to an output piston through a lost motion device. Movement of the output piston causes the displacement of the fluid medium at a controlled rate through the restriction. The output moves simultaneously with the output piston.
