A valve block for a refrigerant circuit comprises at least one refrigerant valve unit having at least one first refrigerant valve and at least one second refrigerant valve which are each configured at least to influence a refrigerant flow of the refrigerant circuit and comprises a valve control unit which is configured at least to control and/or to pilot at least some of the refrigerant valves of the refrigerant valve unit, wherein the valve control unit has a specifically actuatable camshaft for actuating a plurality of refrigerant valves and/or a plurality of pilot valves of the valve control unit, in particular for actuating at least one first pilot valve of the valve control unit to pilot the first refrigerant valve and for actuating at least one second pilot valve of the valve control unit to pilot the second refrigerant valve.

The present disclosure provides a control valve including a camshaft and one or more poppet assemblies. In general, the one or more poppet assemblies can include a poppet carriage that is moveable by the camshaft between a first end position and a second end position, a poppet coupled to the poppet carriage, and a spring configured bias the poppet carriage radially away from the camshaft, toward the first end position, in a first radial direction relative to a camshaft axis. According to some aspects, the camshaft can include a cam lobe that engages the poppet carriage to move the poppet carriage from the first end position toward the second end position in a second radial direction that is opposite the first radial direction.
