Abstract

A control block (1) for a lubrication system has a main body (2) with at least one inlet port (4) and at least one outlet port (6). A primary connecting line (8) fluidically connects the inlet port (4) to the outlet port (6). The main body (2) has at least one return port (10). A relief valve (12), in an open state, opens a connection between the primary connecting line (8) and the return port (10), and, in a closed state, builds up pressure in the primary connecting line (8), for lubricant to be conveyed to the at least one lubrication point via the outlet port (6). The relief valve (12) changes from a closed state to an open state when the pressure in the primary connecting line (8) exceeds a predefined pressure value.

Dependent claims

A control block for a lubrication system, the control block comprising:

a main body having at least one inlet port, at least one outlet port, a primary connecting line, and at least one return port, the primary connecting line fluidically connects the at least one inlet port to the at least one outlet port;
and
a relief valve 12 in the main body, the relief valve is configured so that, in an open state, the relief valve opens a connection between the primary connecting line and the return port, and, in a closed state, the relief valve builds up pressure in the primary connecting line, in order for lubricant to be conveyed to at least one lubrication point via the at least one outlet port, the relief valve is configured to change from a closed state to an open state when pressure in the primary connecting line exceeds a predefined pressure value.
