<p>The pump (22) has a check valve (42) integrated into a valve element (46) of an exhaust valve (40), where the check valve opens to high pressure regions (24, 26). The valve element of the exhaust valve exhibits a valve seat (64) for a spherical valve element (62) of the check valve, where the opening pressure difference of the check valve is smaller than the opening pressure difference of the exhaust valve. The spherical valve element is arranged in a cage (56) that is held at the valve element of the exhaust valve.</p> |
