摘要： The aim of the invention is to improve, by way of a surface activation, the bonding of a cylinder liner mounted in the cast material of a light-alloy crankcase. To this end the surface of the cylinder liner is mechanically roughened. In addition, copper particles are preferably implanted in the treated surface. Care should be taken to ensure that little time passes between surface activation and casting. If possible, the activated surface should also not be touched by hand.

摘要： The present invention relates to a cylinder head for an internal combustion engine of the reciprocating piston type, and in particular to a helical inlet port (1) with a sharp edge swirl lip (18) on a generally cylindrical valve stem recess. The helical inlet port (1) has an inlet passage (20), a bowl-shaped chamber (6) which has a rim that terminates in an annular valve seat (10) and which encompasses an annular space (14) about a generally cylindrical valve stem guide (8) for a poppet valve stem. One surface (25) of the bowl meets one wall (28) of the inlet passage along a swirl edge (18), which has a radius of less than about 0.5 mm, and preferably a sharp edge with a radius of less than about 0.1 mm. Such swirl edges may be formed by casting the inlet port with excess material (24), which is then machined away only within the bowl (6) along a cylindrical cutting line (26).

摘要： The present invention relates to a cylinder head for an internal combustion engine of the reciprocating piston type, and in particular to a helical inlet port 1 with a flat wall portion (2) in a section of the port (20) upstream of a bowl-shaped recess (6) about a valve stem guide (8). The flat walled section (2) meets a generally cylindrical portion of the recess (6) adjacent a cusp-shaped swirl edge (18). The orientation of the flat portion (2) with respect to a reference feature, such as the axis of the valve stem guide (8), may then be used as a measure of the accuracy of casting of the inlet port, and may also be altered if so desired to vary the swirl characteristics of the inlet port (1).

摘要： The method of the present invention comprises the steps of:

providing a first aluminum member and a second aluminum member to be bonded to each other;
forming a zinc alloy soldering layer on the surface while applying ultrasonic vibration to any one of the first aluminum member and the second aluminum member; and
bonding the first aluminum member and the second aluminum member through the zinc alloy soldering layer. That is, the first aluminum member and the second aluminum member are formed by casting. The first aluminum member is thereafter immersed in a molten zinc alloy soldering bath. Ultrasonic vibration is applied, and a zinc alloy soldering layer is formed in a prescribed region of the first aluminum member. Further, a zinc alloy soldering layer is formed in a prescribed region of the second aluminum member in the same manner as in the first aluminum member. Then, the first aluminum member and the second aluminum member are bonded through the zinc alloy soldering layer.

Upon bonding, ultrasonic vibration is applied, or the members are heated to a temperature over the melting point of the zinc alloy solder.

摘要： According to the rodless power cylinder of the present invention, plug members (33) are inserted in the bore (34) of the cylinder barre (31). A slit (32) is provided on the cylinder barrel (31) and extending in parallel to the axis of the cylinder barrel. A piston (40) is disposed in the bore (34) of the cylinder barrel (31) and is movable along the slit (32). An external carriage (44) which is connected with the piston (40) by a yoke (42) extending through the slit (32) is provided. An inner seal band (50) which closes the inner opening of the slit (32) is disposed in the cylinder barrel (31) along the slit (32). The ends of the inner seal band (50) are clamped between the securing screws and the flank of the plug members (33). The securing screw (55) extends through the slit (32) from a fitting plate (53) disposed on the outer wall of the cylinder barrel (31). The fitting plate (53) is secured to the outer wall of the cylinder barrel (31) by mounting bolts threaded into the plug members through the slit (32). Therefore, the inner seal band and the outer seal band can be secured without any machining of the cylinder barrel (31).

摘要： A method for bonding valve seats (1) for intake and exhaust valves to an engine cylinder head (2) and also a cylinder heat (2) suitable for this method are provided. Valve seats (1) are brazed to an aluminum cylinder head (2,32) using an Al-Zn type brazing material (7) and a fluoride type flux (8). The brazing material (7) contains 70 to 90% by weight of Zn. The brazing is preferably carried out at a temperature of 470 to 520°C. o allow the brazing material (7) and flux (8) to be present between the cylinder head (2) and each valve seat (1), the cylinder head (2) contains U-grooves (6) formed around the opening of each intake or exhaust port (3). The U-groove (6) consists of an annular step (4) formed along the opening of the intake or exhaust port (3) and a bank (5) extended along the inner circumference of the step (4). The valve seats (1) are placed in the U-grooves (6), which are then filled with the brazing material (7) and flux (8), to carry out brazing of the valve seats (1) onto the cylinder head (2). After completion of the brazing, the banks (5) are removed to complete bonding of the valve seats (1) to the cylinder head (2). In another method, a valve seat (31) is directly bonded to a cylinder head (32) by applying a fluoride type flux on the valve seat (31).

摘要： A rodless cylinder of pneumatic driving slit type, comprising a cylinder tube (1) provided with a curved part bent in the axial direction, a slit (2) of substantially trapezoidal section formed along the longitudinal direction of the inner circumferential side of the curved tube, a sealing belt (3) whose two ends are fixed within the cylinder tube (1) and which engages with the slit (2) and a piston (4) disposed within the cylinder. The piston (4) has a piston body (5) and sealing pistons (6a, 6b) connected pivotally to both ends of the piston body (5). The piston body (5) is provided with a connecting part (5b) projecting from the slit (2) to the outside and a belt inserting hole (5a) for receiving the sealing belt (3). On an outer circumferential part of the piston body (5) and the sealing pistons (6a, 6b), annular grooves (16) are formed, each of which has a bottom surface which is a part of a spherical surface. A respective wear ring (8) having an inner circumferential surface with the same curved surface is inserted slantwise within each annular groove (16). During formation of the cylinder tube of the rodless cylinder, the slit (2) is formed linearly in the longitudinal direction of the outer circumferential part of a linear tubular material by cutting, and with a spacer (S) (Fig. 7) temporarily fitted into the slit (2), the tubular material is positioned in a recess between a movable die and a fixed die of a bending machine and the movable die is moved along the curved outer circumferential part of the fixed die so that the tubular material is bent with the spacer at the inside of the bend (Figs. 1 and 7)
