The present invention relates to a casting die device (50) and a casting method. The casting die device (50) has a core pin (92) for forming an inner hole (14) in a casted article (10). The core pin (92) is a hollow body, and a pressurizing pin (96) is inserted into a hollow inner part (94) of the core pin (92). Vibrations from a vibrator (120) of a micro vibration machine (118) are imparted to the pressurizing pin (96) via a vibration transmission member (112). The vibrations further propagate to the core pin (92) from the pressurizing pin (96), and then propagate to the area surrounding the core pin (92) in a molten metal (66) that has been poured into a cavity (60).
A filter insertion opening (36) into which a filter (20) is inserted is formed in an indoor-air/outdoor-air switching unit (12) which constitutes an air conditioning device (10) for a vehicle, and a guide section (40) for guiding the filter (20) downstream in the insertion direction is provided on the inner wall surface (52) of a casing (18) so as to face the filter insertion opening (36). The guide section (40) has: a first lower guide (42) facing the filter insertion opening (36) and tilted upward; and a second lower guide (44) formed downstream of the first lower guide (42) in the insertion direction and tilted downward. When inserting the filter (20) from the filter insertion opening (36), the filter (20) is guided along the first lower guide (42) and therefore is inserted while being tilted such that the end of the filter (20), which is located downstream in the insertion direction, is lifted up. Consequently, for example, even if a vehicle body-side structure is disposed above and close to the filter insertion opening (36), the filter (20) can be inserted without contact with the structure.

A first pressing section (35a) of a rotational stop means (26), between a control valve and a slide piece, presses the slide piece so that the control exterior face (8b) is brought in contact with the control interior face (8a) by pressing a first pressure receiver (36a) when operating a screw shaft (29) in forward, and a second pressing section (35b) presses the slide piece so that the control exterior face (8b) is brought in contact with the control interior face (8a) by pressing a second pressure receiver (36b) when operating the screw shaft (29) in reverse. Thus, a gap can be prevented by always having the interior face of the valve guide hole in which the measuring hole is opened and the exterior face of the control vale in contact, with manufacturing errors or assembly errors having no substantial impact.
F02M 69/32 - Low-pressure fuel-injection apparatus characterised by means for facilitating the starting-up or idling of engines or by means for enriching fuel charge, e.g. below operational temperatures or upon high power demand of engines with an air by-pass around the air throttle valve or with an auxiliary air passage, e.g. with a variably controlled valve therein
A fuel injection valve comprises: a spring retainer (36) which is disposed and affixed within a stationary core (5) and which has a hollow section serving as a center fuel passage (50) for connecting the inside of a fuel inlet cylinder (6) to the inside of a valve housing (3); and a return spring (33) which is provided in a compressed position between a rear spring seat (35) at the front end of the spring retainer (36) and the front spring seat (34) of a movable core (12) and which presses a valve body (13) toward a valve seat (7). An outer fuel passage (51) which connects the inside of the fuel inlet cylinder (6) to the inside of the valve housing (3) and which extends parallel to the center fuel passage (50) is formed between the spring retainer (36) and the stationary core (5). As a result of this configuration, the cross-sectional area of the fuel passage around the spring retainer can be increased without impairing the function of the spring retainer which serves as a seat for the return spring.
In a pressure reducing valve, a coupling mechanism (39) which couples a valve stem (27) of a pressure reducing valve body (10) to a diaphragm rod (38) is configured by way of: a bottomed linkage hole (40) provided on the diaphragm rod (38); a reduced-diameter stem portion (27a) provided on the valve stem, and first and second large-diameter stem portions (27b and 27c) disposed on both sides, in the axial direction, of the reduced-diameter stem portion (27a); a holding plate (41) which has a latch recess portion (41a) which is open on one side and allows loose insertion of the reduced-diameter stem portion (27a), and which is fit into the linkage hole (40); and retaining rings (44) which engage first retaining grooves (42) of the outer peripheral surface of the holding plate (41) and second retaining grooves (43) of the inner periphery of the linkage hole (40) so as to allow enlargement along the diameter direction of the valve stem (27). To the linkage hole (40), a set spring (58) which biases the holding plate (41) toward the valve opening side of the pressure reducing valve body (10) is compressedly disposed. As a result, when opening and closing the pressure reducing valve body, occurrence of noise caused by rattling within the coupling unit for the diaphragm rod and the valve stem is prevented so as to provide a silent pressure reducing valve.

[Solution] A gas filter (50) that removes gas from a cavity (14) in a mold (12), and is equipped with a rod-shaped member formed of metal and having slit-shaped space parts (54) penetrating in the axial direction thereof.
In the present invention, at the time of starting an engine using gaseous fuel, energization of a shut-off valve is started and gaseous fuel injection by energization control of a gaseous fuel injection valve is started. Subsequent to starting energization of the shut-off valve, on the basis of high-pressure pipe pressure recognized from the output signal of a pressure sensor, in a case where it was determined that a gaseous fuel tank is filled with gaseous fuel and thereafter determined that a second valve of the shut-off valve is not open, fuel injection is switched to liquid fuel injection by energization control of the liquid fuel-injection valve.

[Problem] Provided is a die casting apparatus configured so that a sensor, which can reliably and easily acquire information on the interior of the die such as gas pressure or metal pressure inside the cavity or metal temperature, can be easily fitted in the die. [Solution] A peninsular detection cavity into which molten metal is filled in the same manner as the product cavity is formed in continuity with the product cavity. The formation site of said peninsular section (detection cavity) is formed so as to protrude from the entrance portion of the exhaust pathway or from a selected surface portion of the die cast product and is formed at a position where the sensor measurement rod can be removed easily from the die. The sensor measurement rod is inserted here and gas pressure, metal pressure, or metal temperature is detected by the sensor.
