Title: Compressor and moving scroll thereof
Inventor: YANG DEVIN
IPC: F04C18/02
Filed: 2023-07-04
Abstract: The present application provides a compressor and a moving scroll thereof. A moving scroll wall of a moving base plate is integrally formed at a first side of the moving base plate, the moving scroll wall extending around an axis from a position near the axis in a direction away from the axis. A collection groove is disposed on an end face of the moving scroll wall, the end face being located at the end of the moving scroll wall that is opposite the moving base plate in the direction of the axis. A channel running in the direction of the axis is disposed between the collection groove and a second side, the channel and the collection groove being connected at a first port, and the channel running through the second side at a second port. The collection groove extends from the first port to a collection end in a direction towards the centre, and the collection groove extends not less than 60 degrees and not more than 400 degrees around the axis from the first port to the collection end. A compressor using the moving scroll has a suitable cost and high compression efficiency.

Abstract: Particulate matter collected by an environmental air quality control device may be in part toxic in nature and thus not readily disposable. By separating the toxic portion of the particulate matter from a nontoxic portion, disposal of nontoxic portion may be more easily accomplished. This separation may be readily effected where the toxic portion is soluble and the nontoxic portion is insoluble, thus allowing the toxic soluble portion to be formed into a solution with a dissolving liquid. The nontoxic insoluble portion then may be filtered from the toxic solution, rinsed, dried and disposed of accordingly.

Abstract: With a syringe (1), it is important that the quantity of pharmaceutical solution drawn up is entirely expelled again and applied, so that no loss of pharmaceutical occurs as a result of residual volumes in the syringe (1). For this purpose, it has been provided that the plunger (5) exhibits an axially directed displacement pin (8), which dips into the tubular connection (7) of the syringe housing and substantially fills this connection while maintaining an axial channel (14). When the plunger (5) is advanced, the displacement pin (8) is run into the interior of the tubular connection (7), so that the residual volume situated therein, apart from a wetting film, is expelled through the tapered axial channel (14) in the connection (7). In this manner, the residual volume is reduced to almost zero. <IMAGE>

Abstract: In deep bore drilling it is usual to use a fluid operated percussive hammer to provide necessary drive for the boring operation. However a difficulty which is encountered with hammers which are currently in use is that the manufacture of the components for such hammers involves considerable amount of precise machining which not only increases the manufacturing cost of such units but also reduces the service life of the components. Some of the typical hammers in use generally comprise an outer cylindrical casing with a feed tube positioned concentrically within the casing and a piston slidably mounted within the casing and over the feed tube to reciprocate therein and impact on a drill bit mounted in and retained at the bottom of the casing. In order to effect the reciprocating action of the piston fluid passage ways are provided in the feed tube and/or the casing which periodically communicate with ports provided in the piston to periodically admit fluid to the chambers above and below the piston to either lift it away from the drill bit or drive it so as to impact onto the drill bit.
