Oil separator for gas-powered combustion engines
View Patent ↗An oil separator is provided to deposit gas fuel contained in the oil components for connection to a gas fuel line to a gas-powered combustion engine, which is a housing with an inlet opening and an outlet opening for gas fuel, one recorded in the cabinet, which gas fuel then is flowable through the filter element, the sealing between a with the airflow associated stream dream and a receipt with the airflow associated outlet opening starting area is, and one in the inlet opening in the direction of gravity below an outlet with the airflow associated oil collection tank to record in the entrance area by gravity separation from the remote oil gas fuel includes. Furthermore, the oil separator a second oil collection tank to record from the filter element expiring contain oil.
1. An oil separator for separating oil constituents contained in gas fuel, for connection to a gas fuel line of a gas-powered combustion engine, comprising:
a casing with an inlet opening and an outlet opening for the gas fuel;
a filter element incorporated in the casing, through which gas fuel can flow, which forms a seal between an entry area connected with the inlet opening in terms of flow and an exit area connected with the outlet opening;
a first oil collection tank set up in the entry area in a gravitational direction under a port connected with the inlet opening for discharging the gas fuel into the entry area, for holding oil separated from the gas fuel in the entry area through gravitational separation; and
a second oil collection tank adapted to collect oil coming from the filter element in the exit area, and situated in the exit area in the gravitational direction under a port connected with the outlet opening,
wherein the filter element is contained within a filter module, the first oil collection tank is contained wholly within an oil collection module, and a terminal module contains the inlet opening and outlet opening, the filter module detachably coupled to a first side of the terminal module and the oil collection module detachably coupled to a second side of the terminal module, the first side of the terminal module opposite the second side of the terminal module.
2. The oil separator according to claim 1 , wherein a gas fuel stream of the gas fuel flowing into the entry area experiences an increase in a vector flow component directed against the gravitational direction.
3. The oil separator according to claim 1 , wherein the second oil collection tank is situated inside the first oil collection tank.
4. A combustion engine for powering a motor vehicle, comprising:
a gas fuel-powered combustion engine;
a pressure reducer for decreasing the gas pressure of the gas fuel routed to the combustion engine, which is connected in terms of flow on the high-pressure side by a gas fuel line with at least one gas tank to store gas fuel, and on the low-pressure side by a gas fuel line with at least one controllable fuel injection valve for regulating the gas flow of the gas fuel routed to the combustion engine, wherein the combustion engine further comprises an oil separator comprising:
a casing with an inlet opening and an outlet opening for the gas fuel;
a filter element incorporated in the casing, through which gas fuel can flow, which forms a seal between an entry area connected with the inlet opening in terms of flow and an exit area connected with the outlet opening;
a first oil collection tank set up in the entry area in a gravitational direction under a port connected with the inlet opening for discharging the gas fuel into the entry area, for holding oil separated from the gas fuel in the entry area through gravitational separation;
a second oil collection tank that collects oil coming from the filter element in the exit area, the second oil collection tank situated wholly inside the first oil collection tank,
wherein the filter element is contained within a filter module, the first oil collection tank and second oil collection tank are contained wholly within an oil collection module, and a terminal module contains the inlet opening and outlet opening, the filter module detachably coupled to a first side of the terminal module and the oil collection module detachably coupled to a second side of the terminal module, the first side of the terminal module substantially opposite the second side of the terminal module.
5. The combustion engine arrangement according to claim 4 , wherein the oil separator is arranged on the low-pressure side of the pressure reducer.
