Abstract

The invention relates to a progressive distributor (1) for lubricant, comprising a housing block (2). The housing block (2) has a lubricant inlet bore, via which lubricant can be introduced into the progressive distributor (1), and multiple lubricant outlets (16), each of which can dispense a metered lubricant quantity to a load connected to the respective lubricant outlet (16). In order to dispense the metered lubricant quantity, the housing block (2) is equipped with multiple metering pistons (6), which are received in corresponding piston bores (4). Each piston bore (4) is paired with two lubricant outlets (16), and the metering piston (6) can be moved in the piston bore (4) and is designed to alternately dispense the metered lubricant quantity to one lubricant outlet (16) or the other. Furthermore, the piston bores (4) are fluidically connected to the lubricant inlet bore, and the piston bores (4) are fluidically connected together via connection bores (10) in order to further conduct lubricant to the other piston bores (4). The piston bore (4) is a through-bore which extends through the housing block (2) and has at least two regions (24, 26), wherein the first region (24) is designed to receive the metering piston (6), and the second region (26) is designed in the form of a lubricant outlet (16).
