V. Description of the invention (1) The present invention operates on a single feed, which provides a forced discharge of bulk solid materials. When the self-tube can be discharged with equipment such as a germanium storage funnel, the present invention is particularly useful (but not exclusively) to improve the flow of granular or powder products. Such a feed with forced discharge is currently called " Air J, which contains a skeleton, this body has the following characteristics:-On the one hand, an accumulator also has a variable volume for rotation to a device, this device is equipped with a discharge valve, the chamber is thus At least one tubular portion is connected to the device, and this tubular portion forms a discharge path with the chamber. A feed chamber is located in front of the piston. In one direction, the piston is affected by the pressure in the feed chamber Withstand the thrust, and therefore the pressure of the gas introduced into the feed chamber, and fill the accumulator one by one. In order to control the gas flow in the discharge path, one of each component is provided , This seat is connected to the sealing mechanism driven or induced by the piston, and the pressure at the back of the piston ensures that it is maintained in a sealed position. When the corresponding pressure in the feed chamber is released, the accumulator contains Discouraged Less action on the front surface of the piston, so it is pulled to the back of the cylinder with a quick impact to open the passage. The opening of the discharge path of the space may be maintained until the space is filled again and pressure is introduced into the feed again In order to release the pressure in the feed chamber, usually a distributor with several channels connects the feed opening of the feed chamber to the pressurized gas source, so the feed chamber can be closed with # 望Or connect to a pressurized gas source and atmosphere.

Description of the invention (2) In order to ensure a good guiding effect, the length of the guiding effect must be at least equal to its lateral dimension. Therefore, the piston was initially a monolithic column The body * is its end-bearing effect in Qi® over a length greater than its diameter. Therefore, the indignation of the piston is equivalent to the size of the _ volume. To limit this inertial effect, we know the hollow cylindrical piston (US- A-4.771.802), the end of which is supported by In the cymbals, however, the distance between the diameter and the size is still maintained therebetween, and thus a bulky valve is formed. To at least partially reduce this problem of inertia and bulkiness, we know a Lang (ΕΡ-0134726) whose piston is supported by the air In the cymbals, and the length is smaller than the diameter, the piston can move freely, but the amount of movement is also limited. Therefore, due to the backward movement of the piston with a low amplitude, a suspect path can be formed with sufficient transverse planes to limit Loss of potential energy, and at least one channel in the surrounding area of the seat. To achieve this, in this known embodiment, the channel connected to the device penetrates into the valve body, and its end is provided against the piston Occlusion seat on the front surface. Then the channel can be connected to the device, the piston and the cylinder can open the Chen-shaped pass. It is directly connected to the accumulator, but separated from the feed chamber by the piston. To create the way to the accumulator, the piston engages into the cylinder with clearance. Pistons with short supporting parts cannot ensure sufficient guidance to avoid pinching in normal clearance situations; therefore, there must be an important clearance. The distance between the piston and the cylinder must also be restricted to prevent foreign objects and powder products from returning from the equipment to the feed chamber, and the pressure in the feed chamber is used to ensure that the paper size is used smoothly in the national sample half (CNS ) Ή specification (2) 0x297 g; ¢) (please pay attention to the matters before you # fill in-install-by the swimming department Shiyang quasi 杂 杓 employee consumption w cooperation Duin 5i 203587 Λ 6 Π 6 V. Invention Description (3) The Ministry of Economic Affairs, Central Plant Development ^ Α 工 消 " Cooperative seal 31. Quick seal and row are limited to the small cross-section of this known valve that can be guided in the piston support during the time it can be guided by the support. The guide is complementary, and when the guide is on the rail and the seat, the guide is equal to the guide W, | Ai 0 In addition, on the back of the no plug, the spring between the back of the piston can borrow the cylinder center. The restricted passage for the rear movement is around the seat and the interior. The release path is kept in a sealed position. The gap, we know a device (PR-A-2.-589.458), in a part other than the part in the airlock It is mainly used when the piston moves. There is a piston on the short support part, and the back is provided with an axis parallel to The piston shaft is connected with a control shaft. The length of the control shaft and the bottom of the gas shaft are changed so that the lateral dimensions of the guide and the rail are in one, to confirm whether ft '-K' u ίll ': whether to restore the feed pressure Rely on a Zen mechanism, elastic mechanism, and the bottom is integral with the piston-guide member with a low degree of backward movement, this guide member has a cylinder and the piston to release it, and is connected to the bottom of the main body of the device. The whole cross section. When the closed length of the piston is connected to the guide, it is stupid. To ensure that this mechanism is embedded, for example, the cylindrical support surface of the screw country and the plug part of the guide piece are against the joint, this The excellent guide with a minimum length is used for the return of the piston, which is infiltrated into the bottom of the cylinder and formed by the coil spring. This bearing part adjusts the center of the Chen-shaped channel to adjust the weakness of the piston emblem. As a result, the second tube-shaped tubular part results in a curved discharge path, which causes potential energy loss and reduces the discharge energy.

Description of the invention (4) This also tends to increase the valve volume, because the mechanism at the back of the piston, such as the added guide mechanism and the return spring, are all employed. One of the objectives of the invention is to broadcast one of the above-mentioned types. This valve is small and has a small inertia. Another object of the present invention is to broadcast a luer with low energy loss. The purpose of the present invention is to provide this type of The valve, which is characterized in that its piston has a substantially truncated cone shape, its concave portion faces its cover, and it houses a guide and a part of a handle, and a sealing mechanism is provided on the front of the basin , Its opening provides an air-tight support on the outside in the air group.

Invention description (6) Therefore, for example, when the space It is separated and enters into the chamber by opening a channel 5 (this channel 5 is connected to the space 2) at different points on the periphery of the opening 29 connected to the discharge chamber 11, and the channel 6 connected to the device 3 is deep into the Nuo 8 And substantially abut the seat in a plane containing the peripheral edge closest to the cover and located in the radial direction of the piston, the seat is located at a point B that substantially includes the peripheral edge most caught by the cover and is located The piston is in a plane facing in. The piston is also basin-shaped, its concave portion faces the cover, and its bottom is provided with an occlusion machine orchid 17, and the opening of the basin is changed on the outside to provide airtight resistance in the air group By function. The piston is substantially frustoconical, for example. The guide and the guide should preferably be cylindrical springs 27 which are advantageously accommodated in the rails, and in the case of the cover, the springs bear against the shoulders 31 at the bottom of the holes 32 extending in the rails As far as the piston is concerned, it bears against the end of the guide, and the hole extends along the handle and ensures its movement by its guiding action. Regardless of the backward movement of the piston, it is, for example, limited to half the diameter of the tubular cross-section of the discharge path. Since the piston is connected to the annular channel upstream of the seat, the discharge path is a straight path, to reduce potential energy loss. Between the guide and the guide, a ring should be embedded, such as made of four-gasified ethylene, to reduce friction.
