摘要： An object of the invention is to always maintain an outer pin holder and a housing in a speed reducer section at their predetermined positions, to prevent damage to such components as revolving members, outer circumferential engagers, and motion conversion mechanism upon a large axial load due to turning or sudden acceleration/deceleration, etc., and to eliminate rattling noise caused by the housing and the outer pin holder. A casing immobilizing member which is fixed to an inner surface of a speed reducer section casing and a housing immobilizing member which is fixed to an outer surface of a speed reducer section housing are provided between the speed reducer section casing and the speed reducer section housing. The casing immobilizing member and the housing immobilizing member are bonded with each other via a rubber member.

摘要： A vane pump includes a casing and a rotary unit rotatably held within the casing. The rotary unit includes a base portion with radially outwardly opened slits extending radially with respect to a rotational axis of the rotary unit and vanes slidably fitted in the respective slits. An annular chamber is formed around the base portion within the casing and divided into a plurality of pump chambers by the vanes. Each of the pump chambers has a volume cyclically expanded and contracted during rotation of the rotary unit to discharge the fluid drawn into each of the pump chambers. The casing includes an inlet port through which to draw the fluid into the annular chamber. The inlet port is arranged to face a portion of the annular chamber extending between a middle position and a terminating position of an expanding section in which each of the pump chambers expands.

摘要： An object is to provide an oil feed type auto-tensioner which can reliably prevent air from mixing into hydraulic oil in the pressure chamber.This tensioner includes a housing (11) defining a cylinder chamber (13), a plunger (14) slidably mounted in the cylinder chamber (13), a return spring (15) mounted in the cylinder chamber (13) and biasing the plunger (14) outwardly of the cylinder chamber (13), the housing (11) being formed with an oil supply passage (17) communicating with a pressure chamber (16) defined in the cylinder chamber behind the plunger (14), and a check valve (18) provided at a hydraulic oil outlet of the oil supply passage (17). The cylinder chamber (13) includes a large-diameter hole portion (19) provided at an open end thereof, in which a snap ring (20) for braking is received so as to be movable therein. The snap ring (20) includes a plurality of engaging pieces (20a) provided at a radially inner portion thereof and inclined in a direction in which the plunger (14) protrudes from the housing. The engaging pieces (20a) have radially inner edges that are in engagement with the outer periphery of the plunger, thereby restraining retraction of the plunger. When a pushing force is applied to the plunger (14) from the chain while the engine is at a stop, the snap ring (20) for braking abuts the closed end face of the large-diameter hole portion (19) and is stopped. In this state, because the radially inner edges of the engaging pieces (20a) formed on the radially inner portion of the snap ring (20) are in engagement with the outer periphery of the plunger (14), the plunger (14) is prevented from retracting, thus keeping the tension of the chain within a predetermined range. This prevents the plunger (14) from markedly moving outwardly when the engine is subsequently restarted.

摘要： In a heat exchanger for performing heat exchange between a first fluid and a second fluid, a corrugated plate is provided in a first tube defining a first fluid passage through which the first fluid flows. The corrugated plate forms ridges and grooves. Walls between the ridges and grooves include first walls, second walls and third walls. Each first wall defines an opening between its second end and a second side wall of the first tube. Each second wall defines openings at its first and second ends. Each third wall defines an opening between its first end and the first side wall of the first tube. The first to third walls are reiterative in an order of the first wall, the second wall, the third wall and the second wall. Therefore, the first fluid makes double serpentine flows each of which makes alternately large and small turns.

摘要： A hydraulic autotensioner has a cylinder having a closed bottom end, a sleeve mounted in the cylinder and a plunger slidably mounted in the sleeve. The interior of the cylinder is divided into a reservoir chamber and a pressure chamber by the plunger which is formed with a passage through which the reservoir chamber and the pressure chamber communicate with each other. A check valve is provided in the passage to close the passage if the pressure of hydraulic oil in the pressure chamber increases above the pressure of hydraulic oil in the reservoir chamber. A return spring is mounted in the cylinder to bias a rod which is axially movable together with the plunger in such a direction as to protrude from an upper opening of the cylinder. The return spring is mounted in a space formed between the outer peripheral surface of the sleeve and the inner peripheral surface of the cylinder.
