摘要： A vehicle body frame of a bulldozer has a left side frame, a right side frame, a base plate, and a cross member. The left and right side frames each extend in the front and back direction. The base plate spans across between the left and right side frames. The cross member is positioned between a hydraulic pump and left and right hydraulic motors. The cross member protrudes upward from the base plate. The cross member spans across between the left and right side frames. The cross member has a left conduit hole and a right conduit hole which are spaced apart in a left and right direction of the bulldozer. The first and second left hydraulic fluid tubes pass through the left conduit hole. The first and second right hydraulic fluid tubes pass through the right conduit hole.

摘要： A pneumatic fastener driving tool includes a main valve operable to cause compressed air to be alternately introduced into and discharged from the upper piston chamber, a first passage leading the compressed air into the main valve chamber, a repeat valve disposed in the first passage for opening and closing the same, and a second passage extending between the lower piston chamber and a repeat valve chamber in which the repeat valve is reciprocably received. With this construction, the repeat valve is reciprocally movable in response to a change of pressure in the lower piston chamber to cause the main valve to reciprocate, thereby reciprocating the piston repeatedly. Since the reciprocating fastener driving movement of the piston is directly related to the reciprocating movement of the repeat valve, the fastener driving work can be achieved reliably without causing any operational failure such as a non-load striking.

摘要： A fastener driving tool such as a pneumatic nailing machine drives a fastener into a workpiece under a fluid pressure supplied into an upper chamber in a cylinder and applied to a piston reciprocally movably disposed in the cylinder. When the fastener being driven is stopped in a power stroke of the piston due to a pressure shortage, the fluid flows from the upper chamber into a lower chamber in the cylinder to make the pressure in the lower chamber equal to or higher than the pressure in the upper chamber. No reactive forces are thus applied by the high pressure in the upper chamber to the fastener driving tool, and the fastener driving tool is prevented from being repelled back when the fastener is stopped. The fastener can then be driven home into the workpiece in successive power strokes of the piston.

摘要： A power driven percussion tool is provided with a rotatable magazine block formed with a plurality of bores about the axis of rotation of the magazine block and is loaded with fasteners such as rivets or nails respectively retained in the bores. When the magazine block is stepwise rotated about its axis the bores are successively brought into alignment with the direction in which the fastener can be driven by a reciprocating hammer. The percussion tool is further provided with safety means for disabling the tool when the tool is not in use or being re-loaded with fasteners.

摘要： An air motor has a rotor rotatable in response to the pressure of pressurized air. A cylindrical rotary member is connected to the air motor for causing a rotation in synchronism with the rotation of the rotor. A rotary slider is slidable in the axial direction along the inner cylindrical wall of the rotary member. A rotational force transmitting mechanism is provided for transmitting the rotation of the rotary member to the rotary slider. A shaft has one end fixed to the rotary slider and the other end equipped with a piston and a driver bit holder. The rotational and axial motion of the rotary slider is transmitted to a driver bit held in the driver bit holder. And, a cylinder guides the axial slide movement of the piston responsive to the pressure of pressurized air applied on a pressure-receiving surface of the piston.
