A retractable fitting with a stopcock has a stopcock housing for connection to a pipe or process chamber. The housing has a connection opening into the pipe or process chamber. A shut-off body is rotatable about a pivot axis relative to the stopcock housing, and has a passage hole that merges in an open state of the stopcock into the connection opening of the stopcock housing, the connection opening being closed by the shut-off body in a closed state. A support element in the passage hole is introduced in the open state through the connection opening into the pipe or process chamber. A plurality of flushing lines are operable to conduct a flushing medium, the plurality of flushing lines being accessible from outside of the stopcock and being connected to and/or opening into the passage hole of the shut-off body at least in the closed state of the stopcock.

A unitized valve body for use in an automatic transmission includes a valve bore and an annulus. The valve bore is configured to receive a valve. The annulus is in fluid communication with the valve bore. The annulus defines an outer portion having an outer diameter and an innermost portion located at an interface between the valve bore and the valve. The outer portion having a first axial length and the innermost portion having a second axial length. The first axial length is greater than the second axial length.

A unitized valve body for use in an automatic transmission includes a plurality of first hydraulic passages, a second hydraulic passage and a plurality of orifices. The second hydraulic passage extending through the unitized valve body and configured to be in fluid communication with a plurality of valve bores. Each orifice disposed within the unitized valve body and fluidly connecting the second hydraulic passage to a respective first hydraulic passage of the plurality of first hydraulic passages.

Flanged fittings with proximal, central, and distal sections between proximal and distal ends, the proximal section including a flange portion with bolt holes, and the central section including curved or angled surfaces, and which provide enhanced structural integrity and function for use in pipeline operations are described. The fittings can include an inner threaded surface capable of receiving a threaded plug to provide a primary seal in the fitting, and then can be capped with a finishing cap at the flange portion following a pipeline tapping process.

A water diverting device is used for fitting inside a porous surrounding wall of a vertical drainage pipe which is deeply inserted into the soil for collecting water from the ground level. The water diverting device includes a tubular wall having at least one slit, and a base wall having at least one drainage port. The drainage port is located at a higher level than a lower slit edge of the slit so as to have a lower level of water accumulated for passing through the slit and an upper open end segment of the porous surrounding wall, thereby soaking the soil near the ground level.

An expansion plug includes a first collar configured to advance as it rotates relative to a shaft, a second collar configured to move axially along the shaft without rotating, a first expanding structure, and a second expanding structure disposed in the stated order on the shaft. When the first collar is rotated in an advancement direction, opposite sides of the second expanding structure are moved closer together to expand the second expanding structure, and then opposite sides of the first expanding structure are moved closer together to expand the first expanding structure.
