A screening bucket (1), comprising two opposite side walls (5), which define at least partially an unloading opening (4), wherein the screening bucket (1) comprises a screening assembly (6), which comprises a screening shaft (7) rotatable about a rotation axis (8) and a plurality of screening tools (9) connected to the screening shaft (7), wherein the screening bucket (1) comprises a transmission system (11), positioned at at least one of the side walls (5) and configured to transfer mechanical and/or hydraulic power to the screening assembly (6), wherein the transmission system (11) comprises a rotor (12) positioned at a side wall (4) and extending to protrude into the loading compartment (3) and facing one of the shaft ends (10), wherein the screening shaft (7) forms, at the shaft end (10) facing the rotor (12), a shaft coupling portion (13) forming a shaft recess (14) open at least in a direction transverse to an axis parallel to the rotation axis (8) or radial to the rotation axis (8), wherein the shaft recess (14) is blind in a direction transverse to an axis parallel to the rotation axis (8) or radial to the rotation axis (8), wherein the rotor (12) comprises a rotor end (17), removably inserted into the shaft recess (14), so as to obtain a geometric coupling with the shaft coupling portion (13), wherein the rotor end (17) and the shaft recess (14) are shaped so as to allow a torque transmission from the rotor (12) to the screening shaft (7), wherein the screening bucket (1) comprises a clamp (18), positioned opposite to the shaft coupling portion (13) with respect to the rotor end (17) of the rotor (12) along a direction transverse or radial to the rotation axis (8), and wherein the clamp (18) is removably clamped to the shaft coupling portion (13) so as to constrain the rotor end (17) of the rotor (12) in the shaft recess (14).

An indoor unit (1), in particular for a split heat pump, comprising a housing (2) that defines a housing compartment (3) inside; a fluid circuit (6); a refrigerant circuit (4); and a heat exchanger (5) configured to facilitate heat exchange between the refrigerant and the fluid, wherein the refrigerant circuit (4) extends between two end bodies (7) configured to convey the refrigerant through the heat exchanger (5), thereby achieving heat exchange with the fluid, wherein one of the end bodies (7) is configured to convey the refrigerant into the heat exchanger (5), while the other is configured to convey the refrigerant out of the heat exchanger (5), wherein each end body (7) includes a shut-off valve (8) designed to intercept the refrigerant flow circulating through the end body (7), wherein each shut-off valve (8) comprises an interception chamber (9) and an interception member, which is configured to intercept the refrigerant circulating through the shut-off chamber (9), wherein each shut-off valve (8) includes a terminal conduit (10) fluidically connected to the shut-off chamber (9) and extending in the opposite direction from the housing (2) with respect to the shut-off chamber (9), wherein the terminal conduit (10) is shaped to enable a fluid-tight connection between the shut-off chamber (9) and an external refrigerant circuit (19), and is formed as a single piece with the shut-off chamber (9).
