Abstract: A handheld power tool (1) is disclosed comprising a power tool body (3), a tool (2), a power source (4) configured to power the tool (2), a switch (10) configured to set the power tool (1) in an active-state or an inactive-state, and an elongated handle (20). The elongated handle (20) comprises a trigger element (30) being arranged movable relative the elongated handle (20) such that the trigger element (30) moves relative the handle (20) when a person grips the handle (20). The switch (10) is arranged at the power tool body (3). The power tool (1) comprises a mechanism (7) operably connected to the trigger element (30). The mechanism (7) is configured such that a first mechanism member (11) of the mechanism (7) is moved in a direction (d1) towards the switch (10) when the handle (20) is gripped.

Abstract: A handheld power tool (1) is disclosed comprising a handle (20) and a trigger element (30) extending along a curved portion of the handle (20) and being movably arranged relative to the handle (20). The power tool (1) further comprises a spring assembly (8) configured to bias the trigger element (30) towards an unactuated position relative to the handle (20) and a switch (10) configured to switch from a first state to a second state when the trigger element (30) is moved from the unactuated position. The spring assembly (8) comprises a follower (9) and a spring member (13) configured to bias the follower (9) in a first direction (d1) against a sliding surface (18) of one of the handle (20) and the trigger element (30) to bias the trigger element (30) towards the unactuated position. The follower (9) is slidably arranged relative to the sliding surface (18) along a second direction (d2) being perpendicular to the first direction (d1).

Abstract: In a cassette for test tubes for use e.g. in a fraction collector the test tubes are kept in a fixed position by means of flexible springs arranged on an adjustable hold and release plate, which, when moved to its release position, releases the test tubes.

Abstract: A hydraulic pump in the form of an oil pump for a vehicle engine has both its pinion, which is driven by the engine's crankshaft, and a ring-gear, which cooperates with the pinion, incorporated in an end-cover fastened to the end of the engine block. A cap is inserted in a collar on the side of the end-cover facing away from the engine and is only held in position there by means of a locking ring, which engages with a groove in the collar and presses the cap toward the engine. Outside the oil pump, a partly socket-shaped belt pulley is mounted on the crankshaft and its socket-shaped portion substantially grips the collar. Fitting and removal are thus simplified and engine overall length reduced. Simplified sealing also reduces oil leakage risks.
