Abstract: [Problem] To provide by the present invention a pressure-accumulation dispenser that can be given a pressure-accumulation function with a simple structure. [Means for Solving Problems] A pressure-accumulation dispenser pressurizes and injects liquid in a cylinder 11 from a nozzle portion 21 to the outside by sliding a piston portion 23 in the cylinder 11 up and down with rotation of a trigger includes a pressure-accumulation giving valve in the piston portion 23. The pressure-accumulation giving valve is formed of a piston valve 51, a spring body 52, and a piston cover 53, or the pressure-accumulation giving valve is formed of an insertion valve seat 54, a piston valve 51, a spring body 52, and a piston cover 53.

Abstract: [Objective] To provide a trigger-type pump dispenser having a cam mechanism which stabilizes the movement of a swing lever and prevents a biasing means for returning a piston from being affected by liquid. [Means for Solution] A trigger-type pump dispenser A has: a body part (1) attachable to an opening part of a container main body; a cylinder part (2) integrally provided with the body part (1); a piston part (3) slidable in the cylinder part (2); a balance arm part (4) pivotally attached to the body part 1 so as to vertically slide the piston part (3); a trigger part (6) turning the balance arm part (4); a spring part (5) for returning the trigger part (6) via the balance arm part (4); and a cover member (8) attached to the body part (1); wherein movement of the trigger part (6) is transmitted to the balance arm part (4) by a cam mechanism.

Abstract: There is provided an indexing table apparatus which has enhanced table rigidity by eliminating a portion for cantilever-supporting the load of the table and which can therefore significantly reduce the deformation of the table due to the load of a large-sized workpiece, thus enabling precision machining of the workpiece.

Abstract: A cover is laterally mounted on an inner assembly which is a unit including all structural elements except for the cover. The cover is fixed to the inner assembly at three portions. A fitting projection provided on the upper surface of a nozzle base is received in a fitting hole formed in the upper surface of the ceiling of the cover. A pair of opposed engaging pieces are formed on the lower surface of a cylinder and the upper surface of a valve assembly, respectively. An engaging piece engaging with a space between the opposed engaging pieces is formed on the lower end of the cover. A horizontal engaging groove is formed in the upper surface of the nozzle base behind the fitting projection on the nozzle base and a projection engageable with the engaging groove is formed on the inner surface of the ceiling of the cover.

Abstract: An induction system and control method for an internal combustion engine that will improve running under low speed, low load conditions by increasing turbulence in the combustion chamber through the use of a control valve positioned in the induction system for the engine. Under high speed, high load conditions, the control valve is held in an open position and thus, the engine is capable of obtaining high output since there is no restriction to the intake air flow. In addition, transient conditions of the engine, such as variations in idle speed, variations in the amount of EGR, changes in speed, such as acceleration or deceleration, starting and warmup, are compensated for by positioning the throttle control valve to obtain optimum performance, and in some instances, the amount of fuel supplied to the engine is also varied so as to improve exhaust emission control and reduce fuel consumption.

Abstract: A dispenser body comprises an upper portion and a lower portion vertically extending from the upper portion. A piston is substantially L-shaped, comprising a horizontal nozzle fixed to the upper body portion and a piston body located at the lower body portion. A cylinder is coupled with a swingable trigger and located at the lower body portion; it can reciprocate when the trigger is squeezed and released. An inlet conduit is formed within the cylinder, whereas an outlet conduit is provided within the piston. A slit is cut in the front section of the lower body portion. Thanks to this slit, the lower body portion is resiliently fitted in a bottle cap and, thus, connected thereto. The rear end of the trigger and the nozzle can pass through this slit. The piston is engaged with the cylinder, and supports the cylinder in its lower position, i.e., the non-operation position of the cylinder.

Abstract: A check valve comprises a valve body and a plurality of blades--all made of plastics and integral with one another. The blades extend straight in the axial direction of the valve body. The blades undergo elastic deformation when pushed onto a tapered inner surface of a stopper at their free ends, thereby biasing the valve body onto a valve seat.

Abstract: A dispenser body molded of plastic material includes an upper body portion on which a trigger is swingably pivoted and a vertically extending lower tubular portion. A piston has an L shape and includes an upper folded horizontal portion carried by spaced vertical wall portions of the upper body portion. The piston is vertically disposed in the upper body portion. A nozzle member is mounted on the terminal end of the upper folded horizontal portion. An outlet conduit, communicating with an orifice formed in the nozzle member, is formed in the piston. A cylinder coupled to the trigger is disposed to slide vertically along the piston within the lower tubular portion. The cylinder defines a pump chamber communicating with the outlet conduit. An inlet conduit communicating with the pump chamber is formed in the cylinder. A compression spring, seated in the cylinder at the lower end thereof and abutting on the lower end of the piston at upper end thereof, biases the cylinder to its lower non-operation position.
