The present invention discloses a sleeve for sleeving on an object, which includes: a first body portion, a second body portion, and a first groove. The first body portion has a first reception portion, and the first reception portion has a first notch, and the first notch is provided with a first fastening member. The second body portion is coupled to the first body portion. One end of the first groove is disposed at an adjacent position between the first notch and the second body portion, and the other end of the first groove extends to an appropriate position along an outer edge of a connection between the first body portion and the second body portion. The first groove is separated from the first reception portion by a first thin wall. One end of the object penetrates through the first reception portion, and the first notch is pressed by the first fastening member so that the first groove is broken along the first thin wall to form a first broken opening. The first notch is pressed and tightened by the first fastening member so that the first body portion and the object are fixed to each other.

The invention relates to a clamp, comprising a clamp band and a pre-positioner, wherein the pre-positioner is designed as a supporting band, which has a partial-circle-shaped region, which extends over more than 180. In order to enable simple production and to prevent loss of the pre-positioner, the supporting band has, at each end thereof, a fastening region bent in relation to the partial-circle-shaped region, wherein the fastening regions are fastened on the same side of the clamp band.

A construction machine having a frame and at least one compaction member is provided. The machine also includes a propulsion system having a hydraulic motor adapted to rotate the compaction member. The propulsion system also includes a hydraulic pump fluidly coupled to the hydraulic motor via a high pressure line and a low pressure line. The high pressure line allows flow of a fluid at high pressure from the hydraulic pump to the hydraulic motor. The low pressure line allows flow of the fluid at low pressure from the hydraulic motor to the hydraulic pump. The propulsion system further includes a hydraulic valve fluidly coupled to the low pressure line and a casing of the hydraulic motor. The hydraulic valve selectively allows flow of a portion of the fluid at low pressure from the low pressure line to the casing for cooling of the hydraulic motor.

An improved hose clamp having an annular band having an inner face, tensioning means, and an annular spring liner; the spring liner having a circumferential shoulder near an edge of the liner; and a central, cylindrical, flat, contact portion of smaller circumference than the shoulder, and of smaller width than the inner face of the band. The shoulder is adapted to abut the inner face and the contact portion is adapted to contact a hose or other article to be clamped.
