The piston valve is biased toward a position at which the oil injection port is closed by a spring. Furthermore, a leak hole which allows oil to be leaked outside of the body from the differential pressure room is formed in the body.

Abstract: A piston cooling jet includes a housing, a nozzle, a valve, a pressure chamber, a pressure adjusting passage, and a filter. The nozzle is provided to project outward from the housing, and capable of spraying oil toward a piston. The valve is capable of moving reciprocally inside the housing, and configured to receive a load due to a hydraulic pressure in an engine-side oil passage applied from a front side of the valve. The valve includes a valve-side oil passage that communicates with the engine-side oil passage. The pressure chamber communicates with the valve-side oil passage. The pressure adjusting passage is disposed between the pressure chamber and a space outside the housing. The filter is disposed in the valve, and configured to remove foreign matter that cannot pass through the pressure adjusting passage from oil passing through the valve-side oil passage.

Abstract: An object is to provide a main tower of a bridge having a rectangle-shaped cross section which can effectively reduce oscillation for wind blowing in the direction normal to the bridge axis. A cross sectional shape of a tower column is a rectangle shape with a direction normal to the bridge axis dimension smaller than a bridge-axis direction dimension. A slit passing through in the direction normal to the bridge axis is formed in a substantially central position, and a ratio of the bridge-axis direction dimension of the slit with respect to the bridge-axis direction dimension of the cross section is between 0.2 and 0.3.

Abstract: Windmill generator sets, each including a windmill and a generator driven by the windmill, are installed on a floating body floating on water. The floating body is formed as a triangular truss structure. Each side of the triangle of the floating body is formed by a hollow beam having a rectangular cross section. The windmill generator sets are disposed on the floating body at the respective corners of the triangle. The distance between the centers of windmills, adjacent to each other, is set at a value smaller than four times, preferably smaller than two times, the diameter of the rotors of the windmills. By setting the distance between the centers of the windmills at a value smaller than four times of the rotor diameter, the construction cost of the floating body can be reduced without any accompanying reduction in the power generation efficiency of the windmill generator sets, whereby the unit power generating cost of the plant can be reduced.

Abstract: In a resin-made throttle body for controlling air flow rate in an air intake passage, orientation of resinous material of a wall of the throttle body surrounding the valve member has a step portion for controlling orientation of fiber-including resinous material. As a result, the inner periphery of the wall can expand or contract evenly as the valve member expands or contracts.

Abstract: Most of the components of an EGR control valve except for a negative pressure actuator, such as a valve seat member, a valve member, a rod, a sliding member, and part of a throttle body, are accommodated in a throttle body and disposed adjacent to an air intake passage. Thus, the number of components of the EGR control valve projecting from the throttle body is reduced, thereby reducing the space around the air intake passage. The rod is disposed in parallel with a throttle shaft, so that a throttle valve and the components of the EGR control valve can be disposed concentratively on the opposite ends of the throttle shaft. Accordingly, the overall size of the recirculation system is reduced.

Abstract: A disclosure is made of a subterranean connecting method and a connecting apparatus therefor which are suitable for use when two shield machines are used to excavate a pair of tunnel sections from both ends of a tunnel, and the tunnel sections are connected to each other in mid course. During underground connection, it is important to secure sealing and water retarding with respect to soil and water pressure exerted by the ground in the vicinity of the connecting section. For this purpose, in the connecting apparatus, a penetration ring is arranged in one of the shield machines, and a penetration chamber in which the penetration ring is accommodated is arranged in the other shield machine. Both the both shield machines face each other with a slight gap remaining therebetween and, subsequently, the penetration ring is moved forward and penetrates into the penetration chamber of the mating shield machine. By this penetration, the area between both the shield machines are closed by the penetration ring.
